ToN tracker+ by Nanashi Arai

This extension adds a bunch of useful features for all the stats lovers :
- Shows your total progress in numbers and percentages (ignores legacy terrors and those such as glorbo)
- A "round progress" page, this displays what percentage of terrors you've survived under each round, under the form of progress bars.
- A few additional counters for survived/mastered terrors.
- A stats page for the round history.
- A Mastery progress page
- A bunch of QoL toggles
- A way to track perfected rounds.
- Unbound round content details

This extension has been translated in Japanese with the help of 0Ask0.

Some features from this extension have made it and more may make it into the tracker itself eventually (and look a hundred times cooler for sure).
