I agree with this. Some users seem to want to keep this feature because of accidental deletions. So let me get this straight. We keep the X key as delete, but since the X key is easier to get accidentally pressed than the Delete key, we have to keep the delete confirmations even though Blender has an undo function for quite a while already? Is this really an elegant design? In Maya, almost all operations are outputted at the bottom so any accidental operations would be displayed. However, most apps seem to get by fine without any delete notifications or confirmation boxes. This would drive people nuts if there were delete confirmations in word processors, Photoshop, audio editors, etc. Why is this needed in a 3d app?
Please get rid of these delete confirmations or give an option to disable them.
