Short description of error
[Please fill out a short description of the error here]
In Edit Mode you will find a toggle to enable Selection mask for sculpting. But you cannot sculpt in edit mode.
Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]
Open Blender, create a grease pencil object. Enter Edit Mode. In the header you will find the Selection Mask mode. But it doesn't work in Edit Mode from what i can see. This is a mode for sculpt mode. As the tooltip suggests. Only sculpt selected stroke points ...
What i also wonder about is the Interpolate dropdown menu. I cannot find it in the documentations. And the visual arrangement suggests that this has something to do with the Selection mask. But in Sculpt Mode it is missing.
