Hi all, we are about to ship SP1 for v21. Question - many have raised the desired behaviors: 1) let me clear a selection in the constraint dialog if I click in blank space and 2) I want a mouse-centric way to commit constraints fast The proposal: When you left click blank space and the constraint dialog is open: If there is 1 selection, the selection is cleared. This lets you quickly mitigate misclicks for the first selection. If there are 2 selections in the input box, commit the constraint. This lets you rapidly commit constraints without touching the dialog at all. Pros: If you know how it works, it's very efficient. No need to touch the dialog or the keyboard for most constraints - just move the mouse to blank space to commit. Cons: The same action results in 2 different outcomes depending on how many selections you have. This may be confusing. It may not be discoverable, and cause confusion. Thoughts?
