 *Additions*
 + Suggest setting variable ~edebug-inhibit-emacs-lisp-mode-bindings~ to avoid conflicts with suggested keybindings.
 + Option ~activities-bookmark-warnings~ enables warning messages when a non-file-visiting buffer can't be bookmarked (for debugging purposes).
++ Option ~activities-resume-into-frame~ controls whether resuming an activity opens a new frame or uses the current one (when ~activities-tabs-mode~ is disabled).

 *Changes*
 + Command ~activities-kill~ now discards an activity's last state (while ~activities-suspend~ saves its last state), and closes its frame or tab.
