I've never heard of Lilyterm before, but the features look pretty sweet. I'm a bit hesitant considering the last time it was updated, but I'll give it a try some of these days.
Browser: firefox-nightly
Bar: polybar (it's tiny at the top for desktop navigation)
text-editor: vim + plugins
Terminal: LilyTerm
Compositor: compton
Lilyterm http://lilyterm.luna.com.tw/
I like the dim when inactive and url link features (http://lilyterm.luna.com.tw/en/features.html).
I also like the lightweight single instance but I do not like how if one term window crashes for some reason they all close---even when i use lilyterm -s.
