I have forgotten I had split tunnel enabled just for my alternate browser to test something and then forgot. I went to a cafe and used their wifi and put my VPN on, thinking I was protected. I was not. All my traffic was unprotected because I had forgotten a day or two ago I had set split tunnel on.

Please add this very very simple UX / GUI feature just to indicate that Split-Tunnel is enabled, in a way you can't not notice. Not requesting a new feature, just a change in the display so you definitely know split tunnel is on.
