> It's far quicker and easier to hit a toggle in JuiceSSH

termux via F-droid is far better now than JuiceSSH Pro. Termux:Widget let's you launch an SSH tunnel script with one click. I stopped using JuiceSSH Pro more than a year ago once I realized this.

I can believe that. But there are ways to reduce this overhead to almost nothing (aliasing, a script, a shell with nice autocomplete...)
