@liaizon Yes 🙂
Since Mastonaut, I'd done two other customized clients in Swift. One based off of Tusker and another based off of IceCubes but aimed more at macOS. I was using the IceCubes based one for a good while and it had all the features I wanted but that was the one which was getting too slow for certain things ...
The Flutter one is a completely new project but it allows me to run on a bunch more platforms than any of the Swift ones did.
