Been doing this for years, haven’t lost anything yet. It works so well that time organizing it would have been wasted.
[edit] “why screenshots?”
1) To record gui workflows, walkthrough-style.
2) to record whole screens of values from guis while preserving formatting perfectly (think: cloud dashboard vital stats screens for various resources)
3) to record short message exchanges from ephemeral messaging with all the formatting intact with zero extra effort. (Think: feature discussion in a periodically-cleaned chat channel; I can always turn it into text later if I need to, recording with screenshot is fast)
4) plus now that it’s almost as easy and reliable to copy-paste from images as from regular text, on macOS and iOS, why not?
For things that are mostly lists I prefer using Microsoft To Do though (I use it ever since it was called Wanderlist)
[edit] in the latest version it’ll even organize your grocery lists by category, for easier shopping.
Idk how long these tools will exist but at least Notion allows exporting to markdown or PDF.
But since it is all in one place I just do search queries using my editor to find what I need. I don’t use tags, but it would be very simple to just append some #tags in my content and search for those.
Haven't set it up yet, but it's on my TODO list.
