Separate color tab

I've been using Pyxel Edit for several months now and I can say I'm absolutely in love this program. I think I'm using it for 80% of my pixel works.
The thing I don't like is the color window. I'm really used to Photoshop sliders, and still don't like Pyxel ones. Also I heard that a color wheel is a good practice for artists.
Also when using a separate window means I lose focus of main drawing window. For example when I tweak sliders and then press B to switch to pen, then the color window registers this press, not the main window. This gives me the most "Damn it!" cases with the program. Could we have a color tab on the side column please? Maybe somewhere near palette.
Edit: forgot to mention color window always covers much of the interface or working space, leaving less space for work.

Those are good points. You can quickly open and close the color window with C, but I agree that would be an improvement.
