it would be great if we could enter a specific HEX code in the color picker of the map scheme editor. I know that it's possible to just enter the HEX codes in the album.style file, but it would be easier to find the part I want to edit in the app's included scheme editor, and it would be more convenient.
Since the colors are stored as HEX codes in said file anyway, I assume it wouldn't be too hard to include as a feature.
I just implemented it, it will be a part of the Navigator since version 4.0.36+. Anyway Android does not have any nice system hex keyboard also the input is not so comfortable.
I looked at Map Customization -> Edit Color cheme -> Default - Edit scheme But I do not see the possibility to enter Hwx Codes in the line and area sections.
