After a few hours of playing around with the Turntable Themes extension, I’m starting to see its potential. There are limits to what can be themed/skinned (bg, colors), but those elements are enough to make a significant difference in how a room looks. And, while the extension needs to be installed locally, the files that change how the room looks are centrally stored.
To coin an old man’s phrase, if you want to “jazz up” your view of tt, this extension does the trick well. Here is an example of the Space theme.
To use this extension, download/install from the Chrome store, then go to your Manage Extensions screen. Click the “options” link for Turntable Themes, select your color/theme then click “Save Options” and (re)load tt.fm.
