Just a thought. It would make using GOG much easier on a phone or tablet.

I've toyed around with the idea of making an unofficial one, particularly for chat which absolutely sucks on mobile. But I'm not sure I have the time (or what the legalities of it might be)

I think even making Forum nad Chat versions for mobile devices would be enough. In Chrome it sucks and Chat is hardly usable (and only after switching to desktop mode).

Gog is bad at websites. Do you really want them on your phone where there's a serious potential for security and privacy leaks??
