There was a question on Stack-Exchange if it would be possible to build *org-agenda* asynchronously. I could not quickly find any good answers neither in the mailing lists nor anywhere else. As I assume this will be a quite helpful feature for some more users, I am notifying you about it here. The question with its answer can be found at https://emacs.stackexchange.com/questions/68123/async-org-agenda/68136#68136 Cheers, Daniel
