I have two tmux sessions (0 and 1), each with a set of windows.  When I run tmux a, I attach to one of the two sessions, usually 1 but sometimes 0.  I always want to attach to 0 if I don't specify a target-session.I've been looking through the manpage and have found the following:tmux a -t 0 - Specify session 0 explicitly.  I'd rather set 0 as the default session and avoid specifying an argument.If a session is omitted, the current session is used if available; if  no current session is available, the most recently used is chosen.There is no current session (because there are no clients attached yet), and the most recently used does not seem to apply: I can detach from session 0 but when I reattach I end up on session 1.  This seems to be time-sensitive; if I detach and reattach very quickly, I return to session 0, but if I wait even 1 second, I attach to session 1.Of course, I can create a shell alias for tmux a -t 0 and use that if there's no way to set a default attach session. I could also swap the windows between sessions so that the ones I want are in session 1 instead of 0.  Both of these feel like workarounds that I hoped would be unnecessary.I am running tmux 1.3-2+squeeze1.
