Referring to the preliminary discussion about this topic started by @Carola_Clavo:
the Feature Request would be
to extend already existing 'Text Find / Replace' -function
for quick text search/replace onto elements inner html
across all scenes/layouts of a multi-scene hype document.
It would be a great time-saver in localization projects when you need to replace e.g. the US-Dollar sign with Euro-sign 20+ times in the same document !
For now only source code editing area (Head HTML tab) is equipped with the
fully functioning 'text find /replace' option.
Those 'text find /replace' functions are all grayed out in scene view,
e.g. in elements inner html.
Here the screenshots:

And here - No options for on-scene text search / find /replace (inner html):
