Per user request, new feature to keep your party in the same order as your slot/windows:

v2.06.02 Adds the option to delay a bit the accept of auto invite in order to have team in slot order.
(you need to set the option on all the windows, not just the lead, also disable auto accept
in other addons like EMA to use this feature; lastly it may not work at login time, if so,
middle click to disband and left click to reinvite, in order)
