Lars' "standard-lars" template is the one that is being used here on openacs.org when we submit postings, bugs, etc. IMHO it's much prettier than the blue "standard" template (which is the default one used in, I would estimate, 95 percent of all forms in the toolkit).
It is "cleaner" than the blue one and better separates the elements. It also does not use <TD nowrap> which the blue does (very annoying).
The only complaint I have with standard-lars - and it applies to the blue template too - is that the element label ought to be valigned to the top. It's irritating to have to scroll down in order to read what the element is about if it contains a bulky text.
It would be pretty easy to rename the standard template to "standard-blue" (say) and then rename standard-lars to "standard", wouldn't it?
Anyway, all in all I think it is a way better default than the current "standard" template.
