I was quite excited about the forms at the beginning (like every new feature ;-) ), but I see myself using more and more the Attributes pane again.
This is because of that unintuitive double scrollbar, + it still doesn't work properly, see the screenshot.
I would much more prefer if the form isn't part of the item, i.e. there would be only one scrollbar. This would limit the length of the item so there could be something that would minimize the form (a small plus/minus in the upper left corner of the form) or even auto-hide like other panes.
For the time being, I'm getting rid of the forms
What is your experience with them?
