I'm a long-time-user of tt-rss. Now I noticed from a german magazine (c't) that selfoss offers an fulltext import and found the tt-rss plugin "readability". So I compared the both features (tt-rss' readability and selfoss' fulltextrss) and the result is that the selfoss variant works much more better (at least due to the possibility to custom configuration of hosts).
=> I wanted that feature in tt-rss!
Now I made a quick-and-dirty-hack to get the (attached) plugin running for tt-rss. It works great (for my few sites with custom configs).
Maybe someone of you experts will beautify this plugin for tt-rss sometimes?
