I have a normal screen protector on there at the moment but there is still quite a lot of glare so I've just purchased another matte screen protector to try.
I cleaned up the home screen quite a bit and now just have a Poweramp widget, Spotify widget, Subaru logo, small clock, weather logo and navigation shortcut. I'm currently working with Tasker to customise operation even more.. Commands like autoplaying music when it wakes from sleep, screen brightness at particular times etc... Any other ideas you have for Tasker will be welcomed.
Here it is in-situ with Poweramp opened playing music. It's not a brilliant picture as it was quite dark and taken with my iPotato.
