I suggest just adding support for something that other people would find useful in the future. Like U<> for URL links instead of L<> for POD links. Then pod2html would make <a href="blah">blah</a>, pod2txt would leave it alone, and pod2rtf would do whatever RTFs do for URLs and so on.

Since the clicky URL kind of link is ubiquitous in just about any readable file format, but the POD standard doesn't really seem to cover it, I expect it would be handy for a lot of people.

If I can go one step further, maybe even add a G<> for inline graphics files. I hate the lack of simple diagramming in PODs, and the cumbersome =for html idiom for all these everyday wants.
