Tmux with a few custom key bindings is amazing. Kind of a learning curve, but not nearly as difficult as something like Vim.

I agree with most of your points. Just wanted to add that I use Git + GNU Stow to manage this exact situation and it works flawlessly.

I’m not sure how true this is.

My Jabra 75 is paired and connected via BT with my Android phone and a MacBook Pro. I can hear notifications or podcasts from my phone as long as I’m not actively listening to something on the Mac. I use this dual device always on config upwards of 9 hours a day with no issues.
