- (2025-06-19) Waadling Penguin: I am the developer on my alt account. To use this effectively (since this is the new user scripts API) you must wrap all your DOM code in a `setTimeout` so you can wait for the page to load.
- (2025-06-10) osirisgothra (osirisgothra): Must be for older or heavily re-policied chrome, because current security policies won't allow for the scripts to run (they give extensive errors in the console, some in which could be disabled but it appears that some cannot). It might also be a chromium-only thing. I didn't test it there. Regardless of the two, it did not work at all for any of my test cases.
