Some feedback and wishess (edited)

Honest answer, because it is just not in my standard profile as I don’t always use these but I use them often.
It is just a comfort or laziness matter. Nothing crucial.
Though I think @Thanatomanic’s suggestions would be a good solution, if it isn’t technically complicated.
Again, this isn’t hugely important it would only be more comfortable, I my opinion.

That’s it! Thanks!!

How about the double RGB curves?
Is that feasible?
