Yihui Xie wants to document the contents of nested lists:
Complex nested lists in R can be difficult to explore and understand at a glance. The

However, I suddenly realized that it can be a very useful tool for exploring nested lists in an interactive way, so I wrote a quick implementation:
xfun::tabset().
