Hello,

Here is a pull request with those two features that seems useful...

Best regards.

@ionut-arm and @Superhepper : i made the changes, thanks for your feedbacks !

[Superhepper]

Rebase it on latest from main. I have merged a fix for all the lint errors.

I updated using github web "update" button : it merges instead of rebasing, but that should be ok.

I think the only missing bit is running cargo fmt locally and committing and pushing the result :thinking:

Unfortunately I don't think we can merge as is now - you'll need to rebase and get all your commits on top of @Superhepper's, otherwise we'll have his commit twice.
