Software applications these days can be difficult to use. It's hard to remember which hotkey does what, or how to start a task, or where to find a menu item. You're smart enough to take notes when you do work it out, but where are you saving those notes, and are they always immediately accessible when next required?
Coalde AppNote solves these problems by letting you make notes for apps by pressing the Ctrl+Win keys while an app is being used. You then edit or read your note, and press Esc to close and auto-save it. When Ctrl+Win is pressed again for the same app later, your note magically reopens where you left off.
