couple years ago, i did try but after hours of attempts, i just couldn't install working version of Eole-foobar-theme, is it possible to run these days?

I've never heard of that. It looks like it packages some dodgy components, notably foo_spider_monkey_panel. I only know that fb2k with its official components work reliably.

Unfortunately, the theme is written in javascript, so this is basically a middleware It was the first and last time i was able to perfectly customize my player to what i wanted though
