Idea button for quick capture of ideas without losing your place

The idea button is to enable quick capture of an idea, always putting them in the same place - the ideas folder, so you don't have to think about clicking in the right place in the navigation bar, and so you don't lose your place in the navigation bar if you are actually in the middle of editing something else. It should be quick, easy, and non-disruptive to capture those ideas that just come at any moment. When you close that idea window you are left back exactly where you were.
Multiple access paths:
- Idea button
- Command sequence e.g. CMD+I
- Ability to email yourself@dabberlyeditor.com and it pops the content of the message straight into the idea folder
