I installed it in my office laptop. You do not require admin rights on the machine to install NoteScraps (I do not have admin right on my office laptop 🙂 ).
The best thing I liked about the tool is the UI is very simple and intuitive to use. If you want to delete a note, just delete the whole content of the note. That’s it – it will be deleted. I remember the first time my father used Notepad – he asked me the same question! Why the text file is not deleted when he has infact deleted all the contents.
Install the app and take a look
