Could you perhaps post your thoughts on some Obsidian forum to see if someone can validate your approach?
With any particular outcome in mind?
Problem is that the Obsidian forums aren't great at analysis.
And this is an issue only to a tiny minority (possibly only me).
I would have expected more informed responses when I first raised the issue if more informed responses were to be had. And no comment from developers at all.
I have a few more tests to do, and recheck on the latest version, and then I'll probably put a small post on the forum in case anyone else is ever interested.
I mentioned it here as a follow-on to my post explaining my change of direction, to indicate that there were simpler methods of managing it. Certainly it makes it easier for me to continue using Obsidian for most notes, but does nothing to move me from Frankenstein.
Which had advantages anyway. I worked out how to do multi-coloured highlights in markdown fairly easily, but simply using RTF is easier still and it is only a temporary stage for me, not the final document. At some point, I'm sure someone will come up with a better form of plaintext for the average word processor user. It will give up document management and document styling features (the latter are rarely used by most, and the former are little used by the average user) ave but keep the text control and styling. It will give up code blocks. Maybe it will be called marktext.
