I would find it very useful if, while adjusting settings in a Filters dialogue (e.g. Offset Paths), I could still use Option-scroll to zoom in and out of the main panel.
cmd++/- does work.
That’s good to know and helpful, but I still would like the scroll method if possible (in part because I find retraining my fingers difficult, but mostly because the Cmd shortcut can’t “steer” the zoom to a particular part of the glyph).
