Nope. I wanted to have both. Besides cycle-or-exec (coe) technically can't replace
jump-or-exec (joe):

a) the case of multiple matches is pretty low as both start an app or switch to it,
more instances must be started manually and since I'm using joe the amount of
windows on my desktop dramatically decreased (yay!)

b) coe is a cycling command, therefore the binding must start with a modifier, fake
modifiers from macros ("nested keybindings") won't work, joe wins here.

even more comfort with the key and name arg. key arg for joe would also be good,
wouldn't it?

Also shouldn't filter-windows-by-name/class go into windows.jl rather than
cycle-or-exec.jl, I thougth so, as they are usefull for other stuff, too.

auf welcher Distribution beruht eigentlich der Emacs, ist doch ein eigenständiges
Betriebssystem, oder? Warum sollte ich mir neben Windows und Linux noch ein BS
aufbügeln? Kann mir da vielleicht jemand ein paar Argumente liefern?
