This is not an idea, per se, and I'm not sure if it's just that Fusion 360 is crashing so often or if it's some sort of data corruption but I keep losing parts after putting a couple hours into them.
That's fine (albeit EXTRORDINARILY ANNOYING and FRUSTRATING) for an application that I'm not paying for but it seems to me that those are pretty major issues for an app that you want to start charging anything for 🙂
I'm not saying you shouldn't start charging.. but I do think you should do a complete freeze on new feature development and spend at least a couple of months focused on stability and data integrity.
When it works, it's amazing and a huge time saver.. when it doesn't, it's madening.
