In Jenkins Administration I often have to take a look at a few jobs at the same time (e.g. history, make config changes). Therefore I open each job in a new tab using Ctrl + left mouse button.
But since the new UI improvements (which are great overall!) a new popup covers the jobs names below the job I just opened in a new window, so either I have to press ESC each time or start from the last job (which I usually forget...).

One Idea: move the popup e.g. 20 pixels to the right.
I would not move it to the end of the job name, because they have different lenght and therefore the popup would appear at a different position each time.
