Profiling Icons Plugin for Intellij IDEA

The plugin annotates Java/Kotlin methods with gutter icons that display the approximate percentage of time the method was executed during the profiling. The profiler snapshot to visualize is loaded using the Tools/Load Profiler Snapshot menu action.

The plugin is a work in progress. It currently supports Async Profiler flat text snapshots only.
