@Angle @lightspill Whatever we can abstract from these in a comprehensible way (e.g. most theming, default file associations, consistent key combinations), we should. Where there are already standards (e.g. CSS <system-color>), we should support them, and ideally use them "natively" unless they're somehow wrong-headed (e.g. screen reader APIs implemented over dbus-based RPC).

It's a lot of work, but it's far from unachievable.
