Feature request: Clicking on the eye icon should close the note

[TriVoxel]

When you open a note, this "eye" icon appears, presumably to let the user know the document is being viewed. However, it is completely useless aside from providing basic visual feedback.

I actually tried clicking this icon to close my notes before realizing it didn't work. It would actually be nice if this icon closed the corresponding note. This would make it a lot easier to manage multiple open notes.
