Finally got #Wallabag working through Docker! For some reason that was completely opaque to me, it was a complete ball-ache to get working with my proxy manager, but finally it works!
I've been using #Karakeep up until now as my article bookmark/read-it-later app, which works really well, but I really wanted to make use of the #KOReader Wallabag integration to read saved articles on my eBook reader.
Was it worth it? Almost certainly not.
Anyway, next on my list to figure out - FitTrackee.
