Display a list of changed files in ToolWindow

Hi,

Could you please clarify what files you want to display in the tool window? Please describe your use case in steps. When should files appear in the tool window?

Also, what did you read that discouraged you from using the BulkFileListener?

I read this, where the person wanted a similar result but was discouraged to use BulkFileListener

Okay, I'll describe step by step what I want

Lets say we have a Java project which was a couple of files 

Program.java

Main.java

Service.java

Once the user edits a file, for example in Main.java user adds a new method

Than the plugin should receive a event and display Main.java file in the tool window

I want something similar to this functionality but as a tool window and the tool window is updated if a file is changed
