My first window manager (on Unix) was Open Look Window Manager (olwm, later olvwm), since this was the default when starting Open Windows on SunOS 4 in 1992. After a few years of mostly using the Open Windows tools, including using MailTool for e-mail, I went through a process of trying to pare down my tooling dependencies to the bare minimum, in order to be able to discover what my actual needs were, so that I could choose better tools appropriately. This included switching from MailTool to Unix mail(1), and using twm(1) as a Window Manager (Not a tiled window manager; the Tab Window Manager, i.e. the basic window manager which was and is included in the standard X11 distribution). I have since switched to more capable mail readers, etc. but I continue to use twm as a window manager to this day. I have found that I simply don’t need anything more than that.
