1.1.0
Adds a Trigger setting: choose which click opens a note in the side group.
Available combos: Cmd+Alt+click (default, unchanged), Cmd+click, Cmd+Shift+click, Alt+click, Alt+Shift+click, Shift+click.
Combos are matched exactly, so choosing Alt+click won't also fire on Cmd+Alt+click. Picking a non-default trigger takes over whatever that combo normally does in Obsidian, and hands Cmd+Alt+click back to its default of always opening a new split.
Custom triggers go through Obsidian's own link handling, so they keep working for links in notes as well as the file explorer, search results and backlinks.
