Create the ability to view a list of all flows not linked to any flows.
I'm currently working on a project where I am currently creating a lot of flows as fast as I can using knowledge from multiple sources, and some of them are unaccurate or out of date.
This results in redundant flows, multiple flows for the same thing, etc. So I end up with flows floating out there that arn't linked to anything and are most likely not required but when linking flows, searching between flows, etc, they'll show up among all the other entries with the same keywords (or letters). I always thought it handy to have the ability to view a listing of all flows, but if PF can show me a listing of all flows, and maybe indicate which ones arn't linked to anything, it would help me do a little clean-up.
The alternative, which I had to do during when our flows were transferred over to another location, was to run 676 searches in the flows (first 2 letters), bring up all the ones I'm not familiar with (hence not linked to anything) and delete them.

We have an "orphan flows" view as part of a "managing flows UI" feature that has not been prioritized yet. We'll let you know when this gets prioritized.
