"Show BTT Preferences" action opens new-style, non-functional preferences window

Describe the bug

I have a BTT shortcut to open BTT preferences. It used to open the same preferences window that I get by double-clicking the BTT app icon or clicking on the BTT menubar icon and selecting Preferences. Now it opens a different window with a different interface, where the buttons don’t work.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):

BTT Preferences

Screenshots

Device information:

  • Type of Mac: 2013 Retina MacBook Pro 15.4″
  • macOS version: 10.13.6
  • BetterTouchTool version: 2.660 (967)

Additional information (e.g. StackTraces, related issues, screenshots, workarounds, etc.):

After I close the new-style preferences window (by clicking, because the ⌘W shortcut does nothing to it), BTT still shows up in the app switcher. I can make it disappear again by opening and closing the old-style BTT preferences window.

Ah sorry, I'm currently using the option key to open the interface which is currently in development. This will be finished in 6-8 weeks.

I forgot you could define a shortcut that includes option to open the preferences...
For now please use a shortcut that doesn't include option, I'll disable the option key check with the next update.

If you re-download the current version from my website it won't open the dev-preferences window anymore. (Sorry I don't want to push it as a new update)
