Close all clones of a same notification bubble with a single click

When several ReplayPoker windows are opened – say the Main Lobby, two Tourney lobbies, one table, and one player profile – and a registered tourney isabout to start, the notification bubbles [View Lobby] and [Play Now] popup in all windows. Currently, we have to click on all crosses to close all clones of a same bubble to close them all.

Idea 1: closing a bubble should also close its clones in other windows.

Idea 2: the [View Lobby] bubble should not popup in the lobby itself when already opened as it makes no sense to open the same lobby twice.
