Hello!
This is a pretty stupid and particular question. But, here we are.
I had some problems with blender crashing, so I did what anyone would dread doing - I reset blender completely to “factory default”. Now, blender seems to be more stable.
The problem is, I can’t figure out what add-on or setting I had enabled before that prompted a pie menu with mode selection, edge mode, vertex mode, face mode etc. by hitting tab. I have tried enabling the usual ‘menu add-ons’, but none seem to bring back this, to me, important function.
What could I have been using before that prompted this menu?
That could be Machine Tools - https://blendermarket.com/products/machin3tools
Im not sure, but afaik HardOps also have similar pie.
