Hi Jeff,
Glad to hear it's getting some use, and I appreciate the feedback! I'd noted this as well and plan to have a think on it.
In the meantime, you can easily add values to the per page drop down list by modifying this:
cmsb/lib/menus/default/list.php
Line 180 in latest CMSB v3.61
<?php echo getSelectOptions($metaData['perPage'], array(5, 10, 25, 50, 100, 250, 1000)); ?>
Just make note of the change for future cmsb upgrades.
Thanks, and please let me know of any other feedback!
Best,
Steve
