I use FairEmail on Android, which aggregates both my Gmail and self-hosted accounts.

I use Gmail's web interface for my Gmail account (which, I'll admit, makes my little rant above more than a little hypocritical)

And in my self hosted email setup I use RoundCube (web interface).

Na, that would simply be the kaleidoscope part you mentioned, wouldn't it? For what it's worth, I found the combination just as peculiar as you did.
