Some autoreplacements aren't that obvious to recognise.
(e.g: i'd like to keep the token short for speed, but if i want to go edit them I'd like to see what my SQL query does without figuring out the code first.)
E.g: "REPLACE(REPLACE(#, CHAR(13), '') CHAR(10), ' ')" removes CR & LF characters from the text, but it took me about 3 seconds to figure out why I had such odd code in a snippet. If I had a simple description field, then I could add "Remove CR & LF characters" in there. (adding it as comment into the SQL Replacement code makes the snippet too clunky to use.)
