Plasma Desktop/Mobile developer here

The first version of Kirigami (the tookit used by plasma mobile) had a very interesting concept around navigation and people hated it. We still have some remnants of this with some floating buttons that are easy to reach for the thumb but also often on top of the content.

I really prefer us to copy a bit the UX of Android/iOS than spending a lot of effort trying to come up with our own UX concept that is not inferior of the one of Android/iOS. We are just an handful of developer and none is paid to work on it.

Please stick to copying the Ux. KDE desktop shines for this very reason that there is no learning curve. First versions should always be heavily inspired by something and later versions can be about innovation.

Thank you for working on KDE!

That's fine, if the Android gestures work well they can feel free to adopt them. GUI toolkits getting not-invented-here syndrome is terrible.

With UX, copying others should be the default: don't make users learn a completely new set of behaviors that aren't the ones they've been using every day.
