Hello, Loving the RSS and filter support in thunderbird and was wishing to get more items in feed. However not all websites have RSS so these features will be useful:
1. Ability to add RSS feed items based on HTML XPATH (Similar to FreshRSS, see here)
2. Ability to add RSS feed items based on JSON dotted path since most APIs use JSON (Similar to FreshRSS again, see here)
3. Ability to add RSS based on std output of scripts (Similar to RSSGaurd and Liferea)
These options would effectively cover all manners of adding a non-RSS-supporting website into feed reader.
