- On smaller screens/windows, the "plugin examples" slides overlap the text at the top, particularly the subheadline/description. Obscuring this text prevents visitors from immediately understanding what the site is about, which could cause them to bounce quickly.
- I'm not a fan of the missing vertical scrollbar, but that's just a personal opinion. It should be noted that it does appear if you use the arrow keys to scroll, but not if you use PgUp/PgDn or Home/End. If you page down and then start scrolling with the arrow keys, you get scrolled back to the top of the page to where you would have been had you used the arrows from the start. It's inconsistent, and potentially confusing.
- I'm not sure about the advice to non-Perl programmers that "if you don't know Perl, you can just use this Rosetta Stone-like page to hack it together using your language of choice as a reference". Again, that's a personal opinion, but it seems like it could easily lead to poor quality plugins.
