I'll add my vote for a dialog editor. Just as long as it's not too much trouble. Actually you probly already have it on your list of things to, so i'll just say Im looking forward to the next update you keep makeing this tool better.
Oh ya, And I would love to see the file trees enhanced to orginize the file types into categories.
I wouldn't mind waiting for the tree to build, but I do have a fast PC.
