We typically have very long publications and trying to find a particular topic in a map requires expanding each parent and child manually. Having the options to "expand all" and "collapse all" from the right-click menu would be extremely helpful.
If you could do this, it would be great if you could also search for a topic in the Content view.
This would also speed up checking for conditionalized topics that are nested under unconditionalized parent topics.
Oracle writers (particularly in DB) would find this very, very useful.
