As a Roblox developer, it is currently too hard to cancel longer running processes in Roblox Studio.
Example: I recently tried to create a Union using a large number of parts. Studio continued to work for over 10 minutes. The green bar at the bottom of the screen continued to move and my cursor rotated. Studio was unusable otherwise. Only after beginning the ‘union’ process did I realize my request included too many, or too complex of parts. I had to completely quit out of the Studio program to cancel the request.
If this issue is addressed, it would improve the development experience because users would be able to cancel long-running processes without having to quit the entire Studio program.
