Love it! It's simple and does the job well. It works for a surprising number of inputs, too (like "in 6 minutes" will correctly use a relative time). It doesn't seem to work backwards, though, with inputs like "4 hours ago", but I haven't needed that functionality so far. The only weird behavior I get is that it pops up anytime I highlight the word "them", which is pretty frequent when highlighting text that's long enough. With text beyond a dozen or so characters, I wouldn't expect to use this tool, so preventing it from popping up on longer highlights would be nice. One other issue I've had is that the tooltip doesn't always respect the window boundary. Text toward the top of a page will lead to an offscreen tooltip, which is pretty rare, but annoying in those few cases when it occurs. Overall, really enjoying this and mainly love that you can completely forget that it's there until you specifically highlight a time.
