If you open a page from the sidebar of the panel, it will open a new tab in your browser by default. It would be awesome if this could be changed or (even better) could be set as an option.
Since I’m using a small “edit”-snippet to link/switch from the frontend to the corresponding panel page, I come up with a bunch of new tabs … because every time I press “p” in the panel to go back to the frontend a new tab comes to live.
At the moment I’m hacking the core. But that’s not really the way I wanna go.
