Searching within Admin menu

I have a couple of feature requests that I would have found useful on a couple of occassions so thought I'd send them in for comment:

Both relate to the types of search that can be set-up within section editors.

1. Allow textfields to be search for via dropdown. Currently, the searchType of "match" only works for lists and checkboxes, but if this was specified for a textfield, could you not run a quick query to generate the distinct field values and populate the drop down?

2. Allow multiple selections. For both lists and checkboxes, the searchType of match produces a dropdown for the selection of one value. It would be great to be able to choose multiple values here. This would work particulalry well with the CSV export add on.

Thanks, Paul.
