You don't have to do that for every application. If there is some
misbehaving application I use only so often, I tend to activate
floating mode (mod+f), start the application, make it floating
(mod+shift+space) and go back to tiling mode (mod+t). But for
applications I'm using more frequently editing config.h and recompiling
dwm might be worth it.

I too found it cumbersome to quit the whole X session just to try out
a config setting for dwm (or upgrading it).

I added this line to config.h:

        { MODKEY|ShiftMask, XK_r, restart, {0} },

and used the following patch to make dwm restart by pressing
MODKEY+shift+r.

It's not perfect, because dwm will not remeber which window has which
tags or which tags you're currently viewing, but that wasn't my main
concern.
