Few questions. Pasting them in one go as it's easier on this side. If possible, let's go from top to bottom, so then none will be missed.

Is there an overview of gestures? Looks like you would be closing lots of apps when coming from SFOS...

There is no pulley menu, right?

In file manager, am I expected to be able to swipe pages back in stack, as in SFOS and Kirigami? doesn't seem to work

Lipstick seems not to scale opened app covers and is happy to go over screen easier than in SFOS

Seems like nemoux is using its own components. I would suggest to look into Kirigami and possibly style it accordingly. its developed actively and is rather open for new concepts/requirements
