Hey @Wimpy. I don’t know if your aware of this one, (i think it was mentioned on Linux Unplugged or Action) but I thought we may consider using Cutegram instead of Telegram in the Ubuntu-MATE Welcome.
I’m not sure if the Official Telegram app is open source . But I’ve been using Cutegram for a few weeks and it’s pretty good. The only issue I have is the tray applet is moody about when it shows up.
Either way, thought I should mention it. …just checked and saw official client is GPL3 …so I guess it would be up to which is better.
