Highlight and Note on footnotes

The realism I posted in a similar thread:

If you observe the search carefully you will see why highlighting footnotes has not yet happened. Why don't the proximity operators work in footnotes? Because a footnote is a single address. To highlight you need either the begin and end addresses or you need a beginning address and a length. Ergo, highlighting footnotes is not a simple extension of the current function. Faithlife knows this is a serious limitation but the cost to remedy it is high. What I suspect will happen is that the technology of the hardware and software will change sufficiently that it becomes necessary/cost effective to have a major rewrite of the software to ditch legacy structures that hold it back. When that happens, we will get footnote behaving like other text.
