feature: supply method to define window classes

[ppenguin]

Default window behaviour is defined in config.h.

Is there a mechanism planned how to configure "suckless properties" (i.e. which normally require recompilation)?

One candidate for this would be the definition of window classes.

Would a possible strategy entail a config frontend which applies changes by sed'ing the config.h and re-compiling it on the fly? Or moving ome functionality from config.h to a config file?

Or one could conceive a more technical approach (probably more robust) similar to the kernel's make menuconfig specifically for feature-based modification of config.h (and other suckless-like utils for that matter)
