Aloha all, LaTeX users are able to define arbitrary float types, e.g. with the float package. The attached patch makes them accessible from Org mode. This is a follow on to my efforts several years ago to support the Tufte-LaTeX package in Org mode, and a suggestion at the time (by Rasmus iirc) to implement an :environment attribute for LaTeX export. This patch achieves a similar goal, but is a bit lighter imo. Let me know if you have questions. All the best, Tom
