The Help menu has Help, Forum, Feedback, and some other items.
None of them, including this "New Idea" area really covers the situation where there's a bug, glitch, crash or other problem with the fucntionality that is already implemented. "Feedback" soulds related but turns out not to be. The forum topic "General Fusion 360 Questions seems to be where some peope have reported problems, but it's not clear tha that's the correct place either.
Desired Change:
Have an explicit "Report a Bug" selection that allows submission of the problam and situation, possibly allowing upload of current program state and undo history etc..
The submissions in this area should get high priority attention compared with new ideas.
It would be fine if they end up as part of the Forums.
