Now, that would really depend on what you consider "more pleasing to the eye and easier to read," wouldn't it?

But we don't know what you consider "more pleasing to the eye and easier to read," which leaves us to offer advice (of uncertain relevance to you) like that excellent offering provided by tobyink, above.

So, you'll have to tell us more... or, better yet, search for nodes (likely in the PerlMonks Discussion section) with some of the words that you'd use to define "pretty" or "easy to read" (and, not just BTW, threads discussing themes already available). Or, if -- for example -- you're looking for javascript to move the sidebar from the right to the left side of your page, you'll find it. If you want pages to render as mirror images, you're on your own.

And don't ignore the PerlMonks FAQ and Display Settings ( provided by the Monastery itself) with its display-control functions.

But remember: so long as you remain an AnnonyMonk, much of that last won't be applicable.
