Allows you to pick a set of variables available within TXP — including from the URL line and the new txp:variable tag — filter them to your liking by variable name or match-by-name/value and then chuck the values at a form so you can, well, do stuff with those names/values.

If your article fields contain further lists of things you can ask the plugin to dive in and treat those as pseudo-variables too.

Very useful if you don’t know how many items are going to be returned in a particular variable (e.g. from some user input in a form).
