Feature_request: color customization about tileboard

You can adjust any colours in the css file as desired however for background of media player I would suggest to simply make the opacity 50% or so:

bgSuffix: '@attributes.entity_picture',
bgOpacity: 0.5

Dont seem to get it working.
Tried with '' around it also

{
position: [7, 1],
width: 2,
title: 'Sonos One - Köket',
id: 'media_player.kitchen',
type: TYPES.MEDIA_PLAYER,
showSource: true,
state: '@attributes.media_title',
bgSuffix: '@attributes.entity_picture',
bgOpacity: 0.5
},

It should work. You might want to clear browser's cache and close the window.
