@elementary Typing this using Olifant on my Pinebook Pro from an Elementary OS 6 preview build. (to anyone who wishes to attempt this, do so knowing that EOS 6 is unfinished software so there are bound to be incompatiblities with EOS 5 apps)
The builds may not have the ability to install apps from the AppCenter yet (probably for good reason), but because these apps are open source, there is no reason that I can't go grab the source code of my favourite app and compile it ;)
