Find in all documents - needs work

[trids]

Currently (TP 5.4.2)
The option "In all documents" on the Find dialog has room for improvement: if i search for a word with "in all documents" checked, then all documents in the current workspace are scanned as expected .. but each time i click "Next", every single open document is repositioned to display its own next occurrence! Which is not much use, especially when windows with hits are lying behind other windows.

Expected behaviour
If i have 20 documents open, and only 5 of them have the target string i'm trying to find, then the "Next" button should take me to each occurrence in turn: one at a time, per document. And when each document is exhausted, then the next document should be brought into focus while its hits are displayed sequentially with each click of "Next". And when all documents have been exhasuted, then focus should scroll back to the first hit again (in the first document) and continue as before.

This represents a logical extension of the plain single-document Find behaviour.
