If you really want to "tag" things in OF, you can. Just put something like "Tag:Boss" or "Tag:XYZ" or even "Tag:Boss Tag:XYZ" in the notes field. When you want to filter on that, just use the find command to search for your tag(s). You can even save perspectives with a find command active if you want one-click access to a certain tag search.

The reason for the "Tag:" bit is to make reasonably sure that you won't have the tag name appearing elsewhere in an action or project name, which would cause it to turn up in searches where you might not want it.
