Great tool this. The ability to configure it means it can be used for generic cleaning. I have a couple of suggestions if you're still working on it:

1) The ability to select multiple entries using SHIFT and CTRL click on the search results and then new right-click context menu items to check/un-check the selected entries. It should be possible to do this from both the upper (ie. treeview) and lower (ie. list) panes.

2) The ability to "Open Containing Folder" from the lower pane.

I don't want to cause any trouble for Rheinhard, but I'm wondering how SMIRF qualifies for entry. I ask because the rules state (I've added emphasis for the bit in question):

You may submit programs you have worked on prior to the contest start date, but you may not submit software that has been previously made publicly available. You are free to collaborate with others and enter as a team. Users are free to submit multiple programs/components.

Does this mean that apps which have previously been released to the public CAN be submitted ?
