VS Code seems to have done away with the timeline history in the source control panel and replaced it with the graph.
I don't care to see so much detail. I really preferred the timeline view. I can live with the graph if I must, but I'm really missing the option to "reset branch to commit" feature the timeline had.
I used "scm.showHistoryGraph": false
in my settings.json. That worked for one release, then they removed that setting.
