Explain the problem as you see it
I want to keep all my day to day information in Tana, and that includes my password lists and some other private information.
But I'm exposed to be onlookers, and i may forget to close the app or change the page.
Why is this a problem for you?
It is not as safe as in other apps like Evernote to keep my password list.
Suggest a solution
Add the option to add a password protection to a node.
Maybe including a "Password" system field to the node.
So that when I want to expand the node or open it as a pge, I would need to enter the password.
