Agree on all the above (used Roam for ~4 months, trying to go to Obsidian). The backlinks here are nominal and provide none of the niceties that Roam provides to actually make them useful.
On major thing Roam does is show more context on backlinks, often by nearest header. So while I care where a backlink is, I also want more context on that link. Displaying the header the backlink falls under (and defaulting to page name) would be super nice.
Additionally, having the ability to filter backlinks by their header. This is what Roam provides and lets me look for backlinks of something like “Automobiles” and filter it by “occurures that appear under the heading of #quotes” to then find quote about automobiles (and then due to headings I can usually see who quoted it). This is all done from the backlink panel, and never needing to navigate to a new page.
