I have an idea for a new feature that I believe will add value to Dropbox.
The idea is to have the ability to create and print an index and sub-indexes for a given Dropbox and the sub-folders.
I spend a good creating an index to my folders, whereas I believe it can be a feature in Dropbox. You can check for example any of my folders (e.g. anything that starts with N+P) and you can see the file that starts with serial number 0.
I am only a user and not a programmer. Therefore, I can't share how to develop the idea.
Don't forget me if you like the idea and you are going to develop it
