Solution:
You currently have the option to increase the amount of rows per page via Data Administration Look-ups in the Admin Tool.
The values for this option come from the 'Grid Page Sizes' (ID=CMN_GRID_PAGE_SIZES) static look-up.
It is a System Look-up so you can't delete or change the current ID values (10 - 50) but you can add your own new values such as 75, 100, or more.
Please be advised that in adding higher page sizes it will place more stress on your system. Please be extremely cautious about doing this and give it some good thought. Do you have the hardware/user load that can handle it
Example:
Once you add the new values any grid/list can be configured to use it. Navigate to the Object List View [Options] page or the Portlet [Options] page.
For example, changing the option on the Project List View to show 100 rows per page.
Go to Administration, Studio: Objects, Project, Views.
Click [Options] for the Project List View.
Set the value to the new value added to the Look up = 100.
