    Love the tool and it has made my practice way more efficient. Highly recommend for anybody getting into speedrunning.

    Also, less conventional, but it's fantastic for golden berry practice. I like to learn the first room, then set an auto-reload save state at the start of that room while learning the second room. So while I'm learning the second room, I have to get consistent at the first because I have to get through it each time. Move the save state forward one room once you feel consistent. Continue this way throughout the chapter. (Make sure you save state before entry to only get entry cycles). Then when you've completed the chapter and have strats, you can use save-states with auto-reload to do mini-goldens for checkpoints or tough series of rooms because a death will send you back to the save state. Very helpful.

    Just wanted to submit 2 feature ideas to consider:
    1. Ability to select checkpoint timing instead of room timing (which allows you to re-enter rooms and time Central Chamber without a flag)
    2. Ability to lock your PB (in case you're timing a potentially faster strat vs a normal strat)
