Option to pin a live histogram above the Roll and Frame tool panels #1370

Could we have an option to keep the histogram permanently visible at the top of the tool panels, regardless of whether Roll or Frame is selected?

When adjusting the black and white points in the Roll category, I cannot see the histogram. I have to switch to Frame to check it, then back to Roll to make another adjustment. This makes it frustrating to judge the effect of each change because I cannot watch the histogram move as I adjust the controls.

Ideally, an optional pinned histogram would:

• Stay visible above the tools in both Roll and Frame.
• Update live as the black and white points are adjusted in Roll, so I can see the effect on the frame I am viewing.
• Remain in the same place when switching between the two categories.

The main thing is being able to adjust the black and white points and watch the histogram at the same time, without repeatedly switching categories.

Thanks for considering it!
