Window always on top mode

I use one of CintaNotes instances as a password manager (love the search). When I register on another site, I first create a new note, type all the fields (login, password, email, name, etc) into a note and then copy-paste them into site registration form.

Ability to pin note's window on top of other windows removes the need to switch windows during this process.

As a starting point, I suggest adding an option to keep all windows of a given CintaNotes instance on top: notes list and all opened notes. This way critical notebooks will be always on top, while others will behave regulary.

Later, all of these windows could be replaced with single window as discussed here:

P.S. "Password manager" scenario is taken as example - it's not the only one that benefits from the suggested option.
