im looking for a app that looks and feels like opening and using different windows on a pc

hey guys, so im doing reaction videos on my android 11 phone, and i have the ability to activate free floating windows, but the issue is that once they are closed out, the size and position will doesn't stay set.
what id love to save have is a app that can easily switch between windows and save the size and position, so even if the phone is reset the apps can be opend and immediately go where i want them to go.

I've tried several apps but haven't gotten anywhere, I've tried probably the most popular app but i don't think it can float any app that i have installed, it looks like it just has basic apps, but i want to float any installed app on my phone.

even if I need to pay for a qpp that's fine, as long is it Will do what i need it to
