netwmpager reports "NetWM compatible window manager not running"
While mlvwm is a virtual window manager and has support for multiple "desks", it doesn't implement EWMH (Extended Window Manager Hints, a.k.a. NetWM). This means that netwmpager reports the following:
NetWM compatible window manager not running
I do not currently plan to build-in a "pager" as the application menu lists & supports switching to virtual "desks", plus there are configurable keyboard shortcuts. That said, some users might want to use an EWMH/NetWM-compatible pager, so it should support that.
Note to self: I tested the original netwmpager 1.11 since it's packaged in OpenBSD ports, but there appears to be a newer 2.0x version available on sourceforge.
The lack of full screen support, Issue #5, is also related to mlvwm not supporting EWMH/NetWM.
