Welcome to TVPaint Community forums !

I noticed some incoherence between the menu and the shortcuts, it's not a big deal, but it could lead to confusions.
In the image menu the function is called Image > Exposure > Remove instance head and in the shortcuts it is called Layer: Exposure: Delete Instance head. I know that sounds like nitpicking, but it's easier to find the right shortcut if the names are coherent.

You're right to pick this kind of mistake. Sadly, there are a lot of "spelling mistakes" (but much less than in previous versions, for we passed on it when preparing version 11).

Thank you for noticing this one !
