As you've found, this tool isn't included in the Fiber Manager toolbar by default (or any other toolbar). There are actually a few Fiber Manager tools that don't appear on the toolbar (e.g. the Fiber Conflict Resolution Tool) and I think this is to keep the UI from getting even more cluttered. The desire is to start with a fixed number of controls on the toolbar, and allow users to customize the toolbar with the features they find the most useful.
It is probably a good time to revisit the controls that are included by default, Brian Mckelvey; it's not a major problem but it is one that would add convenience for our customers.
Ok, no worries.
I might take a look at the other tools which are there this morning, to see if there is anything else which the users might find useful.
