This used to be our workflow too and we built Devarist for exactly this purpose.
Give it a try, would love to hear your thoughts.
Check it out, feedback is very welcome :-)
It's for capturing quick daily notes, supports Markdown, Screenshots, export, daily standup view...
Search is near the top of my Trello board, it's coming soon.
