RBTKID I've been running Hazel for months now and it's made so well that I totally forgot I had it installed. I have it set up to manage my downloads and temporary files, and also to manage my Trash.
Support from the developer is outstanding. I've contacted him twice now and each time he has been patient and helpful. The first time he helped me to debug an applescript of mine, and the second time the problem was tracked down to a bug in another program - he said he would contact that program's authors to file a bug.
Outstanding service and great program!
