UI Networking Approach

Options
I'm having trouble with UI Panels in the scene. (I would use panel for a quest log, or maybe character window etc.)

Example

I'm using PUN Basic tutorial for this example. I have set UI panel in the scene, created the script to activate that panel on button press.

When client 1 enters the game, he opens the panel regulary, when the client 2 enters the game, panel on client 1 gets closed and he has to reopen it. Each time a new clients opens the game, all panels get closed. I'm assuming that is because scene is synced.

How do i avoid this? How to implement networking for UI panels. Should i Instantiate each panel on every client upon loading scene with photonview component so that ownership of that panel has the client? But in that case i will be able to see all panels from all clients in one scene. If that is the case, is there a way to disable all other instantiated clones and only set active the one localplayer has instantiated?

Thank you.
