> wondering what really needed improved

Maybe not much?

A few months ago, I ran out of power (my mistake, I use full screen apps to avoid the distraction, so I didn't realize I was unplugged)

After plugging in and restarting Linux then the ancient version of Word I was using, I got a pleasant surprise: the "autosaved" version of the document I was editing, with nothing lost!

As for llm, Excel 2010 may not have been made for AI, but wine copy/paste and a few scripts work surprisingly well!
