During practice sessions, it’s possible to go from all contexts to their original texts (if they weren’t added manually), but during editing an item or looking it up in the word list, the information is either not available or only available for the first context:
(I’m not totally happy with the look of it so may revisit that at some point, and/or make it so that it’s always there instead of appearing on hover.)
I like the idea of finding all instances of a word in your texts, although this is more work so I’ll have to think more about this and am not making any promises.
