Please help me out....

This app is just awesome as like the way I take my daily notes, lectures and organize them accordingly. But unfortunately, it does not allow me to reopen or edit the file just after saving it. Only delete, duplicate and open with options are available.
Is it me who is having this problem or this app does not allow to reopen and edit the previous documents?
Kindly solve this.
Thanks.
