Ups, I just got to enjoy piped and in particular pipeline on gnu+linux and libretube on AOSP.
Pipeline in particular allows to totally avoid electron (freetube), and in both cases the piped instance is the one communicating with youtube, not me, :) And both applications support sponsorblock (tubular does, but newpipe doesn’t). But not talking directly to youtube is a win. Did I mention dropping another electron app, :) ?
But… I installed pipeline from AUR, because I don’t like flatpak… Not sure if other user repos offer it as well…
Regarding omemo, dino is getting there, see its closed issue 1609. Not sure why it has taken them too long for a new release, but they have the stuff already merged.
