Since I am doing site development alone (for fun), and I hate writing html, I wrote a few utility function that e.g. spit out a simple table from a list. So I use this fairly often since I usually don't want my list to consist of raw db fields and I run some other proc to prettify them before stuffing them in the list.
So I don't know how useful that would be in this day and age of templated sites but I like it. It likely has other applications besides this but that's why I wrote it.
