This is why I tweak and I feel as though RT ought to have a tweak control interface for each part of the structure. e.g. an overall control panel that adjusts the individual elements rather than supply rigid designs that are very difficult to bend into shape through lack of well documented up-to-date structure and specification which must exist somewhere for you all to have done such a great job in putting it all together.
You cant really have an option/setting for everything.
More options always means a slower template.
I can understand the frustration about the documentation – no excuse – but keep in mind RT is a pretty small company that sells awesome stuff for ... "cough"... peanuts.
Only 4 or 5 people do the hardcore coding stuff.
3 or 4 develop the templates.
