BlueRed Diamond - Conditional Formatting on Object
Yellow T Sticky ( looks line a post it with Text icon ) - Tooltip on object
Orange Sunburst - Object script trigger
Green Magnifying Glass - Field available for Quick Find and is optimal ( full index )
Yellow Magnifying Glass - Field available for Quick Find but not optimal ( unstored calcs, unindexed, minimal index with Text fields, etc )
Edit - fixed typo
I've got some fields with little orange & green BBs on them smaller than the magnifier, what are those?
Are you sure they arent just small sized badges? When the field is small they shrink with it such as when using a 1 item checkbox field.
Try turning off the indicator by going to View --> Show --> Quick Find.
Do they go away? Could you post a screenshot?
