I don’t get Spam I just want to be prepeard for the feature because when matrix is growning we will have same problem like with emails ^^

OK this is working nice :)

yea and also than the calandar can work than you can also provide a proton theme.

It exist Thunderbird Extensions for adding a Quick Access to Proton Mail and Proton Calendar. It would be nice the make a Thunderbird Fork or create a Thunderbird Plugin as Bridge.

But i defiantly would use Fedora on this Machine i have a HP Omen AMD Edition with Fedora and its works nice :D
