You've made my day, thank you so much! Atril is really what I've been looking for.
Regarding deadbeef, yeah, it was mentioned mostly on emotional basis. I had some troubles building gtk2 plugin on my home machine, good chances that it was problem with inconsistent building environment, yet no problems with building simple gtk2 apps or deadbeef gtk3 plugin. I haven't dug deeply though. At work, I just use slightly older deadbeef version with gtk2 plugin :)
