Tone map persona - auto-expand/collapse

[AndyQ]

The auto-expand/collapse behaviour of the various subsections in the Tone Map panel is annoying the bejesus out of me. I'm trying to study my image and toggle an effect on/off to see if I like the changes or not, but i can't just leave my cursor in one spot and click as when I disable or enable a function - e.g. curve, white balance, enhance etc. - the positioning of the whole panel changes. I keep having to look at the panel and move the cursor, when I should be looking at the image.  I would MUCH PREFER if these sections were created as sub-panels with their own MANUAL collapse/expand buttons, or some other way be implemented so the positioning of interface elements can be fixed. Also, just because I turn curves "off" doesn't mean I don't want to look at the curves setup (or change it) and toggling on/off is kinda critical to view the effect on your work.

Whilst I'm on this topic - why can't all of these functions just be parametric operations that can be applied in a stack so that they're non-destructive?
