Hi again, I have whipped a few patches against dwm4.7 too... They are all available at http://www.cs.unc.edu/~ritesh/dwm/index.html The climit is basically a twist to clientspertag. It shows the number of hidden (due to climit) windows in the status bar. I find it really useful to see if I have cpt enabled or not because I tend to forget that in the course of my work :). The enhanced (or scrolling) monocle kicks in when climit is set to one (fullscreen) window. In that case, just changing focus changes the client being shown. The above patch requires (quite a few) changes to (only) dwm.c.
I have another grid layout patch which stretches out the first column of the grid (which also contains the master window) if the number of grid cells is higher than the number of windows to show. I haven't integrated it with climit yet so it is useful separately. The patch is on dwm.c is again... but its a single function which can be put in a separate file. Ritesh
