Please produce system filters for source criticism coding

While the scholar has need for searching for the source in source-criticism, the average user simply wishes to see what source is proposed for the text they are reading and where the changes in source occur. For this, a visual filter is the best tool. [Yes, the Andersen-Forbes source criticism visual filters were among the first thing I picked up on the old boards.] Our current primary tools show only what the current word/selection has as source --not where the source changes (I'm thinking Information and Context Menu). Currently this would require entries for: 1) the Source Criticism data set; additions to it should trigger updates to filters 2) the Andersen-Forbes Eissfeldt and Mowinckel coding
