are these features available or could be added?

I have some features I couldn't find in Graphene

Floating windows, I couldn't find an option or a way to make apps get in a window mode.
Auto block Camera and Mic after using?
hide gesture/navigation bar hint?
Hide status bar and navigation bar from the screenshot?

Please do not submit this to the issue tracker as stupidcreature suggests. This has already been requested several times including a recent time in March.

hide gesture/navigation bar

Same goes for this.

If you want apps in windows you can do that via the desktop mode.
The second and third suggestions are quite reasonable. I would suggest submitting them on the issue tracker as a feature request.
I don't see why the fourth suggestion needs to be its own thing - can't you just utilise the crop tool on the screenshot?

Sometimes I need to use it why I can't use desktop.. Also, is desktop mode available on pixels right now? I didn't see it in the settings. I heard they are planing to add it in the future.

Yeah I know I can just crop it but it gets annoying to corp each time you take a screenshot.

So what about my 4th request? should I make a request for it? or some did that?

You can look for any issues yourself, but I doubt there'd be a point to this feature existing as users can simply edit the UI out themselves.

edit the UI by themself? how? with a Launcher?

With an editing app. To edit the screenshot.
