Tomeu, FWIW I've tried multiple times to (politely) make contact with
the original Labyrinth authors since Dec. Not a peep response from
anyone, and the google mail list is dead (authorised posters only and
no one is authorising any one new it seems). Don't hold out hope of
upstream support – I think there's a lot of code in the core that
needing changing to improve UI and a lot of code we don't need to
bundle (custom win NT support!?). I'm guessing upstreaming would work
much better for a project with a well established code-base, and an
active maintainer – we seem to have neither.
I'm happy to fork, and make it work its best for us under Sugar, so we
have a solid activity.
