This is obviously a low priority thing, but still:
Sometimes I think over a position, but then have to go or something before I made up my mind about what to play. In such a case I would like to make notes somewhere - yes, notepad would be great .
My idea is having some "Update" button beside "Notepad" textarea which would update DB with current content of textarea.
Obviously when making a move, "Notepad" textarea would be saved as well as it is now.
