Thanks for your comment! I’ve updated config (now it includes wmaker like dock) and “how to” in first post,
my configuration is much more “complete” now, also some new functions present, that weren’t available in my old config.
Also it is possible to see “how to” for my configuration, including few nice screenshots 
(it is very sad that 300px image limit still exist on fvwmforums.org),
