Live preview in backlinks, improvements to how they are displayed

I am going to close this thread. There’s too much beef in it to be actionable. Please follow/open the specific FR for each point.

I specifically suggest top open one asking for LP in backlinks and nothing else.
There is already a FR for reader-rendering of backlinks https://forum.obsidian.md/t/display-search-results-and-backlinks-in-reading-mode/195
