JW wants the active row in the record table to be highlighted, so you can easily find it again when you've viewed a record then collapsed it again. I've done half of this, in that the highlighting works for viewing records; however, when you edit a record, the original row is automatically replaced, so the highlighting is lost. There are two options to get around this:

1. The MdhRecordList object method writeRecAsRow could have an additional parameter for addHighlighting, which would be set to true by the calling save_rec.php code.
2. The AJAX library sendRequest function could have an optional parameter for a function to call on completion, which it would have to stash in a global variable, then onReadyState could call it at the completion of a transaction, and then set it to null again.

The second of these would be more broadly useful, but more tricky to implement.
