I read #70 and #50 but - even leaving the extensions non-filtered (i.e. any version of the gnome shell, not only 3.4.1) - the extension does not show up on the website:
Not submitted yet. Please discuss in #50.
My bad... I mistakenly took the comment of @Mystro256 in bug #50 as if it was from one of the devs, and expected the extension to be there for 3.4 / after March.
Looking really forward to it anyhow! :)
Sorry bout that. I wrote that in haste and did not phrase that correctly to my intent at all :P
