Plush present the URLs for Downloads, Status, RSS, Config without a trailing "/", whereas the real URL has a trailing "/". This leads to problems when using a reverse proxy (and maybe other use cases): nothing happens when clicking on those links
The link under "Config" is http://...:8080/config , but clicking on it 'eventually' leads to http://...:8080/config/ . That is just like typing http://www.google.com which will result in http://www.google.com/
So I would say that is a minor bug, with big results in my setup.
Solution: have trailing "/"-s in the URLs of Plush in the case it's needed.
FWIW: the 'smpl' skin does present correct URLs with a trailing slash, and that works good via my reverse proxy.
