I updated my Splicer utility to support a 'Run in target directory' option. So you can use it to launch zip, rar, etc files against those programs and it will unzip where the archive was (instead of home dir). Currently that option forces to run in xterm but you can just close it out when it finishes (plus helps to see status).

You can grab it here :

You might need to update the /usr/lib/splicer/splicer.apps list to tweak program list to run against (although the program list allows free entry). I edit config files using splicer itself against leafpad... if your on 2008 and have no good editor to 'launch' against, you can grab 2008 build of leafpad on my http://wardenclyffetower.com/MaemoFiles web space)
