As I said when I talked about how to sync your Obsidian files, you can also sync your settings if you use the Obsidian Sync service. To do this, purchase Obsidian sync then under your sync settings, turn on the sync of your system settings.
You can even choose to sync your settings differently depending on which device you are on. Maybe you don't want to sync plugin settings on your phone, so don't check that box.
Overall, syncing my Obsidian settings has been a very helpful thing in my workflow.
