I use a mix of wmutils[0] and windowchef[1] and they're great, lots of little programs (some < 10 LoC) but also some cool stuff like mouse support and borders etc. I've only ever had trouble with JAVA apps which is a simple fix (_JAVA_AWT_WM_NONREPARENTING=1)
This is a screenshot of my Linux desktop [2], I use these on OpenBSD as well without too much issue.
