We occasionally have customers asking for a way to increase the area the document is displayed in. It’s a pretty easy response for us, as there is already a way to do this built into the ribbon control. It’s called Minimize the Ribbon, and can be used in a couple of different ways.
1. Double click on any one of the ribbon tabs (e.g. Home, Insert and Edit, Review, etc.).
2. Right click on the Ribbon and select Minimize the Ribbon.
What’s even better is that with the ribbon minimized, if you click on a ribbon tab the ribbon will appear, allowing you to select a tool. Once you’ve selected the tool the ribbon will automatically return to a minimized state.

Hello,
This may not be the right place to say - but thought would get your attention.
I think if Nitro PDF has a ‘browse’ feature, it would be great. Adobe professional has this feature. Multiple pdfs should be shown as a list on a left column and on the right viewable area as larger thumbnails (enough to read the text little bit) on the highlighted pdfs should be shown.
This will help, if the file names doesn’t make any sense and helps in sorting and finding pdfs fast rather than opening them individually.
hope my suggestion is considered.
