RGB not just for visualisation

I’m increasingly liking newer versions, but one thing keeps tripping me up: both background reduction and colour calibration work on all R,G,B channels and require a selection but clicking on the RGB view tab gives an error. There’s no need for this; why can’t we just use that view to make selections, crops and background reduction spots?

Because the RGB view was in a separate window in previous versions and we have not integrated the mouse and keyboard control in the new RGB tab yet. It may come…

Oh yes there are needs. It is not just for fun.
Yet siril works per channel. Changing it would be a huge refactoring. So for now it is really better to keep it like that.
