Maybe the app should only be for creating 'quick notes on the fly', eg. IF there were to be some kind of mobile app, I think it should be made to some laser-focused purpose instead of it being just a 'better' mobile interface for the entire suite of tools that is WA.

Great things have already been achieved on the viewing side, I think, but the editing side is indeed cumbersome to use on mobile screens to its full extent. Most likely 'unfeasibly massive.' Like many have already said, I too think that a better use of resources would be to (simply) continue to improve the mobile responsiveness of the WA webpage. You can also cancel it by completely disabling the protection, or you can remove files from the list with a single click, limiting outside access to your files.This would be a massive undertaking. If you want to change the protections for any document, just select or deselect options as necessary, even if you only want to pause it for a few minutes. Once you have everything that you want on your list, you'll see a tab beside each option with six different locks for you to choose from: unprotected, which is self-explanatory hidden, to make it disappear from view locked, to require a password in order to access it read-only, to prohibit any edits to your documents and hidden and locked, to hide a file and prevent access with a special password. There are no limitations to how many folders you can add. To use Anvi Folder Locker, just add items with the 'add' button on the top. The interface is very simple, so even if you don't have much experience, you won't have any problems getting it to work.

If you share your computer with family or friends or just want to protect your files, Anvi Folder Locker is a handy program that lets you hide folders or apply passwords to them to prevent others from accessing the contents.
