[Mapcss] Development of MapCSS?

[Martin Vonwald]

Hi!

Thanks for all the info.

Regarding MapCSS: what would you suggest to get some movement again
into the development of MapCSS. Tagging has become more complex and so
we would need some more features in MapCSS to visualize it.

best regards,
Martin
