Hello!
I am back with a complete rewrite of my app in Jetpack Compose
Why?
Jetpack Compose enabled me to work closer to the OS, to use the wide library of amazing packages built in Java and Kotlin and to have hands-on experience with native Android development. But overall this benefits the app in more features (opening a file in another app for example) and better performance (no need to duplicate the file when we import it, or to copy it when we want to read a video off of it).
The future of the app
I think this app is quite close to be completely finish, minor functionality like searching through files and moving them are trivial to do. If you have any feature requests, don't hesitate to create an issue to tell me more about it!
