How to change to 'Dark Mode' (Coldplaying app)

Something I didn't mention originally. If you want to change to a dark background within the Coldplaying app (More info/DL links here), simply click on the sidebar to open up the menu, then there should be a settings icon on the top right. Once you are on there, a check box option for 'Dark Mode' will appear. It will ask you to reset the app which is fine, just proceed then the app will reload with a dark theme :)

There's also an option to change the font size if the text is too small or large for you.
