I have made several RSS/widget suggestions in the past which you have added to you code. Now I have one more, very minor, improvement suggestion.
Over the past several months I have noticed some HTML tags cropping up in RSS titles. I know that you remove HTML codes from the text but do not do so for titles. If you could add the following to the rss.lua official release I would be greatly appreciative.
title = string.gsub(title, "<.->", "")
Simple and effective:)
Thanks for always keeping the Shadow4 widget add-ons updated with your latest releases.
