Fixed
- The settings page stays where you left it in Chrome. It rebuilt its whole form after every write, so the control you were using was destroyed and replaced mid-change - and Chrome uses the focused element to decide where to hold the page, so it nudged upwards each time you changed a setting. The form is built once now and the controls are updated in place.
- The popup waits for Chrome before closing itself. Opening the settings page returns a promise there, so the window could shut before the request had been accepted, and a refusal went nowhere.

Added
- The settings page and the popup both show which version you are running, read from the extension itself.
