Currently if select one color in palette and click "New Style", OT duplicate selected color, Then you can change that color in "Style Editor".
if possible when user choose color in "Style Editor", if There was not that color in palette, By clicking "New Style" that color add to palette directly.
I think this is useful and fast for create new color in palette.
Somewhere I saw a Style Editor mockup depicting the “New” button next to “Apply” but I can't find it right now.
Another sleek solution for adding new colors to he palette. Hope to see it implemented.
So this could be a duplicate request.
@inkapnea Maybe you saw this mockup.

I kindly repeat the request to add the "New Style" button if feasible. Thank you very much, OpenToonz is shaping really great month after month!
It's a nice idea, though I think it would only be possible with "auto-apply" turned off.
Based on the discussion in #1207 feature requests are going to be closed here on GitHub unless there is a developer actively working on the feature. Feature requests can be discussed at the OpenToonz Google Group: https://groups.google.com/forum/#!forum/opentoonz_en
