over 70 templates sounds excessive IMO, but i know the level of detail you talk about here nothing bad in a little scrollbar or such, agreed with the former statements, good point, +1'd :D
way to go until then is keeping "template" ship (could imagine like stickshippish with branches for the templates) nearby with easy-to-grab copys i guess? maybe one could outsource some from the menu like that... its not a beautiful solution ("Latin" can be quite beautiful for such cases it seems, i dont speak it, too, tho ^,.,^) for the issue itself, i know, but something i tend to use quite often, like nothing undoable neither...
