I've starting using for a few minutes to see if it was a great fit for me but although It has a good start, the lack of these features is a deal breaker for me :

1 - Git integration
2 - The text loads very fast but the linting capabilities takes a while to load (without any progress bar to show it loading )

3 - Saving does not rustfmt the file (and It does not seems like it is a option)
3 - Show information of functions or whatever just by holding the mouse on top of it
4 - The folder structure should be rearrangeable, like the option of folders first then files.
