Extend PRAGMA playback to support javascript selections #5
Description
Currently the https://pragma.archivelab.org/playback/:id interface only works if an annotation is saved having a value of {"id": "xxx"} where xxx is some css ID which can be found within the Save Page Now'd webpage. It would be nice if an annotation could save a javascript selection and the /playback javascript was capable of (after loading the desired pragma wayback ID to playback) surrounding the selection with a span which could then be styled. i.e. extend citations to arbitrary selections (or at least also support css classes) instead of just css IDs.
Some of this work has been started here:
