Edge Panels are a samsung only thing, but I use a similar app on my phone.

I use it less as a dock and more as a way to access stuff I want to quickly be able to go in and out of.

For example, the 2fa app I use auto closes when I copy something to the clipboard, so I just swipe into the app, copy it, and I’m back where I was.

Its also great for apps I don’t use frequently enough to want on my home screen, but when I do need them I don’t want to hunt around for them
