Add the option to select the display of more documents from folders on the same page

[iuliabalan]

Currently when you have more documents/files in a folder only 15 are displayed by default on the same page, then the others are on the next pages.

It would be useful to have the option to select the display of more documents (have more options for the user to select if they want 30, 50 or more documents listed on a page)
