Wmtunlo is a dockapp of little value, leaving the choice of whether to utilize it or not up to the user.
One small bright spot is that wmtunlo does offer some customization. You can assign three programs to run when you perform a double-click. Just take a look at the options in the wmtunlorc file for details.
In terms of updates, the command line options have been replaced by a config file in the latest release. Additionally, thanks to a patch by Alan Jurgensen, you can now run up to three programs on double-click instead of just one.
Overall, if you're looking for a useful dockapp, you may want to keep looking. However, if you are curious about wmtunlo and want to explore the limited customization options it offers, it may be worth a try.
