Long shot, but I don’t suppose there’s a way that one can use custom colour values for the glyph/layer colours?
I know there’s more than enough choice already, and that the colours are easily distinguishable from each other and varied; but I could use the ability to control the exact colour value without any conversion on import/export. UI would be gold, but even via the API would be good - it appears that it’s limited to setting by an index integer at present.
