I'm visually impaired and GW's polar bear in a blizzard (low contrast white) default (and ONLY) color scheme will not work for me. I've read about the skins, but their only applying to the graph colors is really a misuse of the term 'skin'. The term 'skin' w.r.t. applications applies to the color scheme for the entire GUI for the application. Due to impaired vision I must use a high contrast black color scheme (ala what is available in Win10 by that same name). Your application should detect what OS GUI color scheme is in effect and tailor itself to match that color scheme as best it can, or at least allow the user to select alternate GUI color schemes (which MUST include 'dark' color schemes).
I'd love to buy the Pro version of your product, but I cannot do so until you offer a high contrast black complete GUI color scheme. I look forward to that coming soon. Thanks.
