"Select Opened File" is delayed several seconds on a large project.

[kreiger]

I was commenting on https://youtrack.jetbrains.com/issue/IJPL-48480/Project-View-show-selected-file-does-not-work with how "Select Opened File" takes many seconds to work.

Then i ran the Async Profiler to discover that this plugin was slowing everything down.

Uninstalling the plugin has fixed the issue.
