It would be beneficial for users to have the option to switch the display of buttons on the Role Assignment page to text only rather than the full buttons. It would as well be helpful to include the ability to resize the rows or columns to better fit the display. Currently, the Role Assignment page has large "previous" and "next" buttons at the top of the page and the rows and columns are wider than some users prefer. Adding these options would help improve the usability of this page.
The following scenario illlustrates this behavior:
1. Create a new user
2. Create 12 new roles, some with long names(15 characters or so)
3. Navigate to the new users edit page
4. Click Roles on the right side
5. Click Select
On this page, you will notice the large buttons and wide rows/columns.
To add an option to customize these elements, either through portal properties, toggles, or another means, to make them better fit user preference.
