## New

* Added the ability to disable the theme picker via `disable-picker: true` under `theme` (thanks @NeoNyaa) 
* Added `mod` function (modulo) to the custom API widget (thanks @anant-j)
* Added `safeHTML` function to the custom API widget which prevents HTML from being escaped (thanks @sudoexec)

        username: ${USERNAME}
        password: ${PASSWORD}

  # useful if you need to send JSON in a request body
  template: |
    ...
    | withStringBody (.Options.JSON "request-body")
    ...
