@dml0sc “Some time next week” ended up being a couple of weeks, but here’s the first version of the timeline plugin!
I’ll figure out how to get it to the Obsidian community plugins list a bit later. For now, you can get the release files from here: Releases · taneltm/obsidian-year-timeline · GitHub
For now, you’ll need to place the files manually in your vault’s .obsidian/plugins/obsidian-year-timeline directory.
@holroy Added the daily notes integration you suggested. It’s experimental and disabled by default. You can hover over the timeline to see a tooltip of the target date, then when you click it should open the daily note on that date.
@megclaypool Of course I need testers! If something’s buggy or you get new ideas, it would be great if you could write them in the GitHub issues 
It should be backwards compatible with the CSS snippet version of the timeline, so if you used that before. You should probably disable the CSS snippet when you use the plugin.
