I used to use a .txt file like this for over 10 years that I edited with Vim and could also edit on my phone using Dropbox. And then I used the Mac Notes app and realized the search, sync, autosave experience, and other properties made Notes way more useful for me.

Similarly, for over 10 years I used to compile my CV with LaTeX using a fancy template I designed, until I realized the time it took to edit it was just not worth it. So I pasted it into a Google Docs file with Arial font and just text bullet points and no rich text features. My life became way easier and my CV looks way less annoying.

(This may be irrelevant to the original post but) I found that a lot of the optimizations I thought were good for me were stemming from an unnecessary attachment to a minimalist technical aesthetic.
