Konqueror Sidebar TNG: modules layout/order limitations #277

(Per discussion with @hunter0one in the unofficial TDE Matrix room.)

Description

The KMultiTabBar widget used by the Konqueror Sidebar does not:

provide a way to change the module order, which seem to always get sorted alphabetically by their internal name.
save the user's preferred layout when multiple tabs are open (see Hunter's screenshot).

Looks like a limitation of KMultiTabBar itself.

When saving the profile with a custom sidebar order and restarting, this is the result:

You can probably tell how this is annoying. I had the Root Folder module set above the Metabar. I'm sure Blu knows more than I do about this, but I'm almost positive it's not even considering the sidebar layout when saving a profile, it only knows which modules are open (and then arranging them alphabetically by their internal name as Blu said).

which seem to always get sorted alphabetically by their internal name.

The order does not seem alphabetical, rather new panels are added at the bottom. Closing and reopenign the top panel location gets the panel at the bottom.

Would be a nice improvement to be able to drag-drop panels around and also save the layout.
