 We already talked several times in the past about rewriting the application, but for different reasones we 
didn't do it. Now that the [matrix-rust-sdk](https://github.com/matrix-org/matrix-rust-sdk) exists, which 
does a lot of heavy lifting for us, it gives a good starting ground to build Fractal without the need of 
implement every single feature from Matrix API to the user visible UI. Finally with the rise of GTK4 we would 
need to rework and rewrite most of Fractal's code anyways. Therefore, it just makes sense to start over and 
build Fractal-next with all features (e.g end-to-end encryption) we want in mind.
 
+Issues that target fractal-next should be labeld accordingly with the label "fractal-next".
 
 ### Milestones
 The milestones are an unordered list of features we will need to implement (help is much appreciated 😀️)
