We've recently released more filtering options when looking to add gauges to a dashboard or report. You'll see a link for Filters & Sorting that you can expand.
Once you expand the list of additional filters and sorting will help you locate your gauge faster and easier. Filters now include Folders, Datasources, Created By, Chart Types, and sorting has options for last modified, created date, and alphabetical.
Just another small way to make BrightGauge easier and faster to use!
