Dockable items / customizable layout.

[vain]

Notes, preview ports, timer, ... all those could be dockable. This would allow the user to arrange everything as he likes.

While we're at this: How about configuring preview ports on the fly?

Don't forget feature which saves the layout.

Dockable items can easily be done by using GtkHandleBox'es. However, these boxes do not allow to swap items -- they keep a hard reference to their child and only allow this widget to re-dock.

On the experimental "exp-dnd" branch I tried to implement swapping via Gtk's drag-and-drop facility. This is more of a proof of concept than a finished feature. Main development will continue on the master branch.

You can drag ports around as well as the frames of note pad and timer. It works quite well, I guess.

I'll close this feature request in favor of #27.
