thanks your reply.
in fact,except some functions,it works on a7 too.
of course ,i'll look into it and let it more compatible.
well, from the download statistics.there are over 130 140 men download it in a week.
it've made me very happy already!!
i just treat the plugin as my private try in plugin developing and for my team's project(a FPS game, i work as coder).
this plugin doesn't cost me lots of time(i've only spend 4days, 3 hours each day)in the first version and of course doesn't cost lots of time to upgrade it.

i just hope some guys ues it and some of them think it's useful . it's enough
