If it's any help to you, I have around 40 or so of the best DockApps on my site:
http://distro.ibiblio.org/pub/linux/...load/DockApps/
Nearly al these have been updated recently so that they work with recent versions of WindowMaker and can be compiled with gcc>=3.4.
I don't have more of them because most DockApps don't justify the screen space they take up or are just useless *period*. If you had some sepcific apps or categories in mind, let me know. I may have the sources for them or be able to find them and fix them up just like the others.
I have always used WindowMaker and have a nicely patched version on the same site:
http://distro.ibiblio.org/pub/linux/...wmaker-0.92.0/
This version includes the runbox history feature. The way the DockApps above are fixed, they acn be run with wmaker 'dockless'. That is, I use it without the dock or clip being on the desktop. i use the old ROX-Filer and take advantage of its' superior handling of desktop icons and also use taskbar or fbpanel as a panel app. But I also have other choices on my site so you can put together whatever combination you like.
Also have various other wmaker goodies -like the sound server (also updated) and wmakerconf.
Just go up a few levels from those dirs and you'll find about 500 GTK-1.2 apps, 15-20 window managers and plenty of other goodies... i believe I have the most complete collection of light-weight desktop items ever assembled in one place.
