there is a big problem with the plugin that can cause RSS-feed problems (so that those are no longer accessible).
It seems that you are cutting off app titles after 30 bytes and append three dots to then in order to have a short form to display. That is nice, but:
Take a look at the Appstore game with the ID 351338209. It is called "Baphomets Fluch: The Director’s Cut".
Unfortunately this leads to problems on multibyte character strings as you may cut a multibyte character in half.
In my case this breaks all RSS-feeds that contain this specific article with this specific app. Those feeds are no longer accessible.
It would be great if you could fix this problem by rather cutting off after 30 characters than after 30 bytes.
