Thanks @brian
I do agree with you, choice of name is very important.
Busy studying examples and the notes for QT qml and seeing which would be the best way to apply tooltips without them becoming annoying.
As regards fixing the alpha problem, I’m wondering if it’s worth it for just this filter.
It can still be used just not when alpha is required.
Your time and effort could probably be better spent on other areas of Shotcut, like adding VST support, hint, hint
