I have hundreds of filters dedicated to individual dashboard widgets across our JSM site. I have just been adding "(Dashboard Name)" at the end of each filter to specify what it belongs to, but I can never get the search option to work so I have to scroll until I find the one I'm looking for!
I wish they would add a grouping function where you can create a Filter group so all you would need to do is click the group to see all the relevant filters!
Also, I know you can filter out by the owner, but they should also have the option to save it as a user preference so when I go into View All Filters it would automatically show the filters I own.
I'm curious if anyone else has thought about this!
