Fusion 360 often stops responding when something it doesn't like a user parameter or a parameter in a command dialog. For example, if I have fat fingers and accidentally tell it to pattern something 1000 times instead of 10, it may just show a beachball for eternity - forcing me to Force Quit the entire application (probably losing work in other tabs). It would be extremely useful if Fusion 360 could monitor itself and do something like what Google Chrome does when it gives a user the opportunity to kill an unresponsive script/task or keep waiting. This becomes a particularly common problem in Fusion 360 when User Parameters are involved since one change to a user parameter can trigger a lot of calculations. The beachball shows up often in these cases, which is a shame since that's usually where interesting things can happen in Fusion 360... with parameters and complex models.
