+* bugs
+
+- There is a pretty strange bug in kig when you use the accel keys.
+   Open Kig, type p to start constructing a point.  Click somewhere to
+   construct one.  Now click p again, and press escape to cancel the
+   construction.  It will not work, and you will have to construct as
+   many points as times you pressed escape ( or perhaps the times you
+   pressed esc square or sth like that ).  Anyway, this is due to how
+   Kig works with some strange Qt event loop stuff to make its modes
+   work, along with a strange way in kaccel of working.  I have a
+   patch against kdecore/kaccel.cpp that should fix it, but the real
+   fix is to get rid of the entire event loop stuff and think of a
+   better way to manage all this. pino: seems pressing the stop button
+   n times, where n are the times you pressed escape, cancel all the
+   constructions, so the problem is the behaviour of escape.
+
+- The polar coordinate system blocks Kig when zooming. Select the
+  polar coordinate system, use the Select shown area tool ( or your
+  favorite zooming tool ) and select a specific part of the document.
+  Smaller parts of the document cause bigger problems. pino: this is
+  due to the polar grid: try to make zoom if there is no grid.
+
+* I/O: filters, exporters, ...
+
+- add other command line options, like:<br />
+  -e, --export-to FORMAT file.kig => Kig will export file.kig ( or any
+  other supported format ) into file.ext ( even more than one file ).
+  The output format depends on the FORMAT string. domi: this is more
+  difficult, because the export plugins require extra parameters.
+  E.g. the ImageExporter needs an image size etc.
+
+- filters: more input filters; improve the existent ones ( see
+  filters/*-filter-status.txt ); add the possibility to ignore errors
+  on loading
+
+- "export to *": add stuff like java applets, kmplot documents, etc...
+
+* objects
+
+- Two new transformations: projection on a line, orthogonally and
+  according to a given direction.  As a mathematician, I'm supposed to
+  have a grudge against these, as they don't fit the definition for
+  affine transformations ( the matrix has to be regular ) ;), but I
+  suppose high-school students may find them useful.  However,they
+  would give rather useless results for e.g. lines ( all curves are
+  almost always projected on a line, segment or ray that you wouldn't
+  see because it's equal to the line we project upon ).  It would be
+  useful for points though.
+
+- make DoubleImp a "visible" object with uses like Dr. Geo numeric
+  values.
+
+- Provide some nice stuff for differential geometry: velocity vector
+  of a curve, curvature vector, osculating parabole. Most of this is
+  not too difficult to implement, but very cool :)
+
+- create a formula label to display math formulas in the document, and
+  allow for importing from/exporting to other formula formats such as
+  KFormula, OOFormula and MathML.
+
+- other types of fillable shapes, like arc sector, arc segment...
+
+- defined integrals, as a particular case of filled shapes.
+
+- improve *a lot* the transformation support for cubics.
+
+* GUI
+
+- make stuff from RMB menu's accessible from other places as well.
+
+- Add the possibility to select, via new dialog, one or more types of
+  object.
+
+- add a magnifying glass/zoom window to magnify "on-the-fly" a part of
+  the document.
+
+- improve the KTextEditor interface in the script code wizard.
+
+- make the dialogs not pop up over the main window.
+
+- add QTooltip and QWhatsThis to the widgets in the various dialogs
+  (export dialogs, types dialog, ...)
+
+* core
+
+- When selecting an argument of a certain type, maybe we should check
+   whether the required arguments are really there, before telling the
+   user to select them.  Then we could give an error telling the user
+   to first construct the other objects.  An exception should be made
+   for points of course.
+
+- Add the possibility to attach text label also to angles.
+
+- add the possibility to transform more than one object at one time,
+  using the popup menu. For example, I select two circles, I choose
+  Transform->Translate form the RMB menu and then Kig should ask me for
+  a vector to use to translate all the selected objects.
+
+- add support for work with other measure units (cm, inches, etc...)
+  than just pixels...
+
+- extend ObjectFactory::sensiblePointCalcer to also construct
+   intersection points of stuff... (pino: done for lines)
+
+- when moving an object that wants to move its parents, try to check if
+   it is itself not an indirect child of one of the parents it is
+   trying to move, and forbid the move in that case, as it will lead
+   to chaotic behaviour.  I am not sure if this is really well
+   possible, but I have to look at it.
+
+- add intersection types: arc-arc; arc-conic; arc-cubic; conic-cubic;
+  cubic-cubic; locus-other object.
+
+- rework the ObjectConstructor and GUIAction stuff into something more
+   general, and more clean.  See the comment for
+   ObjectConstructor::constructMode().
+
+- figure out a way to allow the user to enable and disable certain
+  features.  E.g. I have been asked to allow the user to limit himself
+  to compass-ruler constructions..
+
+- add another viewmode ( which would be completely orthogonal to the
+  KigMode concept ), where you can more clearly see the dependencies
+  in a figure.  Something with colours, numberings, and/or a tree-like
+  text representation of the dependencies..
+
+* scripting
+
+- Python scripting: export cubics for real, improve existing API.
+
+- make the scripting system work more like the macro system. Make it
+  a way to define new object types that can be reused more than once,
+  instead of making it just a way to add *one* object.
+
+- support for more scripting languages than just Python.
+
+* other
+
+- document mathematical i18n strings, so that the translators have a
+   clue about how to translate them !
+
+- write cabri-filter-status.txt.
+
+- add "Tools": easy tools designed for geometry, like Angle converter and
+  so on...
+
+- save a "session", i.e.: record how a document is moved, and save it to
+  e.g. a flash file or something like that.
+
+- koffice support ?
+
+* future ?
+
+- there should be a way to link a figure to a (html?) file containing
+   exercises.  Teachers would be able to create exercises for Kig.
+   I'm thinking of doing this with HTML (& KHTML) + scripting ( but
+   this is _distant_ future.. )
