Well said and relatable. Often, there are lots of stuff to learn during work is which is then forgotten and needs to be re-learned again and again. It's a wasteful cycle.

Aside from the traditional note-taking apps, some ideas would be using something like Otter.AI or Voiceliner app for quick voice memos to capture thoughts on the important stuff to note. Or use something like OBS to record a computer work session so can then later refer to it (but this is still just an idea that I haven't actually used or refined that much)
