Week 10

This week

• I've added drag and drop support to the custom toolbar panels and the top bar tool shelf. Any operator button can be dragged to it and a button will be added to it. This could possibly be improved by also copying over the operator properties that have been set for the button.

• The operator redo panel is now a floating panel in the bottom right corner of the 3D view. It can be kept open or closed and sits right next to the properties panel if it is open.

• The operator icon making has kicked off with blurymind's work: http://www.blenderartists.org/forum/showthread.php?305240-Operator-ICONS-for-Blender-s-Shelf-panel

Next week

• Fix some outstanding issues with the redo panel.
• Add features to remove and order buttons in custom panels.
• Start work on reorganising the current toolbar panels.
