user interface suggestions

Love this module. Have some suggestions for improving visual appeal and ease of use.
How about...
1. move the options that are left of the operator (permission, status, created, etc.) into maybe three dropdowns. This wd limit how many filters you can apply on the first go, but how often do folks need to filter by 8 criteria all at once? Tradeoff would be cleaner look and more quickly apparent how it all works.

2. tighten up vertical space between filters

3. move "filter" button to bottom of the form (or duplicate it there). My logic here is this: you have to go to the bottom to see your results. So there's alot of scrolling involved in checking results and filtering again. If 1 & 2 work out, 3 is probably moot.
