Today I added support for custom colors in selector, I also added this selector in the layer creation dialog to replace the R/G/B/A inputs.
The next steps are:
- Add functions to set the selected color and line width (when editing)
- Make connection with layers widget and every selector, to show a preview for ByLayer values.
- Add unit tests for color and line width selectors and update for layer creation dialog (edit will be probably broken)
