Hello.

Can you add the keep current settings for selected pen?
When I change penA to PenB and draw something and back to the PenA then PenA is set to default (size).
I need to keep pen settings after Pen change. It would increase my work speed.

Until this feature is not implemented I can not use this tool.
Thanks.

Press F5 to open the brush editor and check "Temporarily Save Tweaks to Presets" -- this should be on by default, but somehow that got broken.
