Pretty confident in my solve. The only ones I didn't get myself were 20-down, 29-down (obvious in retrospect), and 21-across (inferred the word, but didn't know the tool).

You can imagine my face reading the response of 15 lol I thought it was going to be a specific program hahaha I had a lot of fun with it and there were just a few I missed so I would love to see more like these in the future :)
So... Anybody smarter than me know that 24 across is. I thought something like showering/bathing because supposedly people don't like to shower/cleanup as cons but neither seem to fit. Then I thought friends but that doesn't make sense either. So I got nothing.
Edit: Remove the ING from showering and it fits. Gotta check the connected ones to see if it works, though, assuming I get those right.
Edit Edit: I absolutely hate the "Best WM (Wayland) one because that is too subjective to be able to be answered correctly, if you ask me.
Nice. I solved 22 (with 2 of them being unsure), there's 12 I don't know. I can only assume the multiple listings of 'List files in current directory' is a deliberate joke because you use it so much, but somehow it doesn't feel right.
You should find a website to share it where people can play it interactively! I'm sure such websites are out there, it's too obvious.
