did T2, T3 templates today. Other thing when using "cycle user template + factory build queue templates" is that while one can use "(1)", "(2)" type of names for ordering in the GUI, it does not work for the hotkey. For the hotkey, one has to go into Game.prefs file and position templates by hand.
So for hotkey use, one would have T3 fac templates, then T2, then T1, so max available level is on the first position, so no toggling.
