1: When I add a node to the curve to smoothen the upper part (so it doesn’t clip to white but progresses slowly instead) it creates that weird knee-like pattern. Is this supposed to be like that?

Yes, sort of. We have changed the spline interpolation procedure. It seems this is catching a lot of people off-guard, so we are trying to fix this for the final release. See also:

Curves behaviour changed (in development version)

Hello everyone, I’ve noticed that the curves tool in custom mode has changed in behaviour. In V5.4 stable release, it behaves like any other curves adjustment tool I’ve used, most notably Photoshop. When I place a control point in the shadow region (<50%) and raise it, the upper section of the curve gets pushed upwards a lot and one has to watch out for highlights getting clipped and usually will have to add another control point in the highlight section to roll off the curve there. I’m also p…

curves: restore old DCT_Spline, add new DCT_CatmullRom type

2: When messing with the colour channels in the tint section, once I am done with that channel and switch to another, the changes go away. Practically only All channels at once, or just one of the three can be altered.

You need to use different regions for modifying different channels:

3: It would be nice if one didn’t have to choose between curves either being colour or luminosity. Would be nice to have settings for both changing.

this is neither a bug nor a regression.
