Hey, we have merged support for the Color devices, actual colorful displays still testing. Let me know if you would like to test it. Happy to get any feedback on this.
Yes, issues is where we are talking currently, though we have started a sub on Reddit too for those who are not on GitHub and want to share suggestions, bugs, app requests /r/CobaltForKobo
Current priority is a stable SDK, support for oauth and token for adding apps like Dropbox, read later ones etc. and a larger app ecosystem eventually.
