New Editor Tab Action for plugin

First, you can use EditorTrackerListener and `com.intellij.codeInsight.daemon.impl.EditorTracker` to listen for events.

But, probably, creating a window is too much of a distraction. 
For example, you can register `com.intellij.ui.EditorNotifications.Provider` to create a notification panel on top of Editor when it is opened.

>And should this be implemented in an application component or project component?
This choice depends on what you are trying to achieve. Most likely, you're interested in a project component.

Thanks a lot, it works for the most part. Right now, I'm creating a dialog box that asks the user if they want to initiate the log recording. If the file that's going to be logged is already in existence, it works fine, but every time I create a new file and a new tab is created, it hits an error when I press any buttons that's a part of the dialog box(even the X button), "AWT events are not allowed inside write action: java.awt.event.InvocationEvent". I think even switching to notifications won't help. Any suggestions?

EditorFactory editorFactory = EditorFactory.getInstance();
editorFactory.addEditorFactoryListener(new EditorFactoryListener() {
    @Override
    public void editorCreated(@NotNull EditorFactoryEvent editorFactoryEvent) {
        //remind.java is the JDialog class I'm using
        remind.main(new String[]{});
    }

You need to wrap your code into `ApplicationManager.getApplication().invokeLater(Runnable)`.

IIRC, switching to notifications should help as well (and will prevent focus stealing by dialog).
Ex: // inside listener

 Notification notification = new Notification("My Plugin Name", "Enable Logging", "Track document modifications and do smth", 
 NotificationType.INFORMATION);
 notification.addAction(new NotificationAction("Start") {
   @Override
   public void actionPerformed(@NotNull AnActionEvent e, @NotNull Notification notification) {
     // do smth
   }
 });
 notification.notify(project);
