1. When ever you want to access only your work Notezilla sticky notes, Go to work memo board in the Notezilla Notes Browser, on the right, in the top list, press Ctrl+A so that all notes get selected, right click on the list and choose 'Stick to Desktop'.
2. Whenever you wish to access your home notes, go to home memoboard or personal memoboard in the Notes Browser, on the right, in the top list, press Ctrl+A so that all notes get selected, right click on the list and choose 'Stick to Desktop'.
3. Please note Before this (#2) step, you would need to go to the previously visible memo board and select all notes and choose 'Remove from desktop' from the same menu.
Note that, the right click menu will not work for removing the notes from desktop. Use the Notes Browser's 'Stick To Desktop' button on the top toolbar. It will show Remove from desktop option. And of course the "hide" functionality is not the same as "remove from desktop".

What you asked for is currently not possible in Notezilla as the Sync feature is definitely automatic in Notezilla and it will sync all your Windows sticky notes every minute.
