• Open a java file in a java project
• close the side bar (cmd+b on mac)
• navigate to a new file from the same project
• side bar pops up
• repeat ...

This is extremely irritating when trying to step debugging into another file, the debug view is replaced by the explorer. Also looks bad when performing a live demo with limited screen real estate.

Dependency view sync with opened files should only work when the side bar is visible.
