Moments' Tracker allows you to track all your favorite movie/media moments and scenes.
Bookmark your favorite moment, give it a title/caption, and that's it.
Once you've done this, you can jump directly to your moment anytime you open that media file, no need to scroll through trying to find certain moment.
If you just want to mark your position so that you could resume from where you stopped, you could use the "Checkpoint" feature.
Click the "Checkpoint!" button, and retrieve it whenever you want using "Retrieve Checkpoint" button.
Whenever you open a media file, all your bookmarked moments are displayed so that you can manipulate it.
To install Moments' Tracker, download moments_tracker_V1.lua file, and add it into the following destination:
