non standard usergroup setting by RSForm Pro user plugin

it would be great to implement the abillity to set different usergroup(s) by Rsform pro user plugin. I used another extension named extendedereg for this solution, it works but it is to buggy , to many javascript conflicts are produced. I payed 40$ for this extension, but for a production site it is not really useable.

Also it would be great to implement an Filter section to filter submission by their values...

Search input field accept only one string (one field) to display submissions, it would be great to implement a like search to have more serch flexibility.

Thanks and best regards. (I love your extensions!!!)
