Many thanks for the feedback guys, it is much appreciated.
I have been testing it myself and I've come across a slight problem. It doesn't cope with .desktop files which have more than 1 Action entry (e.g. ark_servicemenu.desktop or build-spec.desktop). Presumably, this is because it wouldn't create such files itself but it does limit it's usefulness. If you try to edit an entry you only get presented the first entry in the file and deleting any entry deletes the whole file
It looks like the author hasn't worked on it in almost 2 years so I might have to fix it myself
I'll see what I can do
