SideleafNeu

I wanted my notes with me wherever I work or travel, instead of leaving paper sticky notes on a wall. So I built Sideleaf: sticky notes tucked into the edge of my Mac. Hover to peek, click to write, then move away and they tuck back in. Quick notes, checklists and reminders stay beside my work. I also wanted to rely less on disposable paper sticky notes.
