One thing that bugs is when I click on a planet's name, it takes me inside the system. 95% of the time I just want to know where it's at on the galaxy map. If you know where it's at, it's just a simple click on it to enter the system. Another solution would be to add the exit via right clicking so that it takes you near the system on the galaxy map. The way it's set up now, it exit's you back to the Empire Management screen.

It would indeed be incredibly useful to get pointed to where a system is in the galaxy. Whether it is the default behaviour or an extra button doesn't really matter.
