allow to use HandyNotes as an app, not only as a widget

Please allow to use HandyNotes as an app, not only as a widget.

Currently HandyNotes can only be used as a widget: You add a widget on screen, enter some text and have it displayed there. This will of course work for many people, but not for all. As far as I'm concerned I don't need/want to have my notes so visible on the phone desktop. And they take a lot of space:

• If you want to have one note per widget, you will end up with a nr of widgets cluttering the desktop;
• If you want to put all your notes in one single note and keep the widget small, you might as well use a simple text editor for that;
• If you want to put all your notes in one single note and use a big widget, then it would take too much space.

I would suggest that you add an 'app mode' to HandyNotes. It could work as follows:

• The app can be run as any Android app, via desktop shortcut or Quickdroid
• Loading the app will present the user with an 'add note' button and a list of notes
• Hitting the button will create a note and bring up the current 'edit note' mode
• Hitting any item in the list will pop up the same 'edit note' mode
• Long-pressing any item will bring up a context-menu with the Edit and Delete options

The interface would be very simple, similar to AK Notepad or (the incomplete) Tomdroid, but the usability would be greatly enhanced.
