I have read some of these ideas that are in the works and thought I would give a wishlist that I hope can be applied to future versions.
The main thing is a framework that allows plugins to be created that wont effect the core but add features.
The reason for this would be to add something like tinyMCE or CKEditor inline editor to edit specific elements. I could also make different features available per site.
Adding a more robust image editor, adding the ability to easily replace images and the ability to add/edit background images.
Adding a function that duplicates certain elements.
Add ability to easily create themes and placements for the toolbar.
Thanks for the script and I look forward to v3!
