Very useful, but could use a few UI tweaks.
I used it successfully to remove a bunch of things I installed but forgot about. The location and date along with owner really help you figure out where things came from. This is a very useful utility.
The details tab is useful telling you what is in the plist or lines in the script. Very nice!
Coloring of the services wasnt intuitive to me, I was expecting black to mean editable, gray uneditable, bold user service, and non-bold default service. However it seems my assumptions are almost exactly opposite (from reading the app description in the store) black is user service, gray is default service, bold is uneditable (not able to unload), and non-bold is editable. The "Info" button is supposed to give you the legend you need, but the first time I clicked it I was on the "Others" tab, and nothing happened. Finally while writing this review I discovered how "Info" adds a legend to the actions window. Possibly a better UI would always show the legend in a seperate window if you click "Info".
However since the version 1.2 update, the right click context menu is awesome. I found it better than expected. Not only does it allow you to "Reveal in Finder" the plist that executes the program, but also "Reveal in Finder" the executable itself. So you can manually disable or delete services running on your computer.
Although its great that I can remove the "Per-User Services" this app doesnt have the privelages to remove "System Wide Services", however most apps escilate the privelages by asking the user to provide admin credentials. This app does not escilate privelages, and leaves it up to you to do it the manual way in Finder, "sudo" in Terminal, or reportedly run the app while logged into root.
The bottom line: I found it very useful, because it had a complete listing of the startup locations I knew about, and some I didnt know about.
