Hidden tagging/naming in visitor list
It would be nice to name (or tag) a visitor in the visitor list (e.g. by its company name) without the visitor recognize this (name changes e.g. the visitor recognizes too). So an agent is able to detect his VIP/Key accounts from the list (without opening a visitor and reading the comments).
Also, this would be able to stop certain triggers firing for existing groups of visitors. For example, we could tag all our customers "customer" and then stop a certain trigger firing for that tag.
Adding tags via the Dashboard is quite a basic functionality in my opinion. So, please add an extra formfield to the dashboard for adding tags.
And, suggest often-used tags while typing :)
