suggestions
make the left side of the screen non-clickable - the popups for comments and file attachments have way too much active area of the screen (where the screen seems to be blank). I would like to use the white space to bring up the browser window and the popups get in the way. Oh, and pleeeeeease allow for Esc key to close the attachment and comment popups and in fact all popups, it is a good practice. I hate your popups as a result of the above.
allow for deletion of a project (I did not find how to do it in the project settings
fix the bug that sometimes I cannot add the bar on the timeline for a task (after doing a small drag&drop) and I have to delete and recreate it
add simple undo, I don't want the super complicated undo most of the time, simple ctrl+z should remediate the havoc I have created by accidental messing with the timeline
overall this is an awesome tool!
