Thank you very much for the explanation. I just tested your line of code and undo-tree does get enabled in new buffers. I'm starting to think now that this should be the default Evil behavior, as Evil requires undo-tree to function properly (i.e., it does not make sense to have Evil enabled without undo-tree-mode, when undo-tree is available). -L _______________________________________________ implementations-list mailing list [email protected] https://lists.ourproject.org/cgi-bin/mailman/listinfo/implementations-list
