To be fair E always had great potential (I recall reading somewhere some car makers use it in their infotainment UIs), but alas doesn’t have the manpower to keep it at the same pace as some other DEs, even much newer than it. If I were Xfce and got the last straw of the GNOME-ization of GTK I’d rewrite all my shit with the E libraries - hell, it would be awesome if those two merged together.
Last time I talked about Thunderbird here on Lemmy (and was downvoted because, allegedly, Thunderbird and K-9 are the exact same app, according to android@lemmy.world), I seem to recall it was however mentioned one of the differences between the two is that Thunderbird was going to include setup for Google play subscriptions (whatever that is)…
