 * `font` - overall font. Defaults to `Roboto`.
 * `background` - path to background image. If not set, falls back to `color_bg`. Not set by default.
+* `parallax_bg_shift` - shifting of parallax background on tab change in pixels. `0` disables parallax motion. Negative values will scroll background in opposite direction. Default is `20`.
 * `color_bg` - main background color. Defaults to `#222222`.
 * `color_button_bg_idle` - button background color (in idle state). Defaults to `#888888`.
 * `color_button_bg_hover` - button background color (in hover state). Defaults to `#aaaaaa`.
