dostana Lets of hope upgrade to latest version is in pipeline with the Solus team.
Already planned and we have a tasklist on our development tracker about it.
Integration to Software Centre for flatpak, Snap & AppImage and built upo sources like from github would be a good idea.
I don't really know what you're referring to about GitHub, but the plan is to support Flatpak and Snap in a future release of Software Center.
The world is moving towards icon based systems like android like gui. I think Solus team should give it a thought in future to have a desktop like android or work closely or merge or team up with other teams to bring a standard gui desktop.
