[Enhancement]: Add "spinning dots" when accessing Playlists (and maybe Collections)

[ZLoth]

Describe the Feature/Enhancement

Currently, when the ABS pulls data from the server such as library contents, a spinning three dots is being displayed in the app. However, this does not occur when accessing the Playlist (and maybe Collections).

Why would this be helpful?

There have been times where I have tapped the playlist button... and nothing happens for several seconds. Same when accessing the actual playlist... I have tapped several times while it was processing in the background.
