Add ability to keep properties open after changing

Use case or problem

When clicking on different files while the pre-existing loaded file has open properties, it will close them down when returning back to it.

Proposed solution

Maybe a setting inside the properties core plugin to keep it open when changing files?

Current workaround (optional)

Reopen each time you go back to the file.

Maybe not to make the properties tab feel like a generic header and give it a UI handle that feels unique to it? Honestly, it’s a cool feature but just doesn’t look the part…
