Looking for a long lost friend (program)

I used to have this program which was an Add-on adder tool thing that had game mode SVN downloads, tools svn downloads, and map svn downloads and stuff. It used to install add ons and disable/enable them.
All I recall is that the icon was a brown box looking thing
If someone can re-connect our love, it will be great.

Is this what you are looking for? Its similar to what you described

Gman mod manager ?
