Best money I've spent on accessories since I purchased the bike.

So what else have you bought ? And how good / useful have you found it ?
I definitely want a dark screen, it's a white bike so I think it needs it. The BM one is €260. Sure I can get nearly 3 aftermarket ones for that price !
Also on my 'list' are levers. I really hate the standard, non-adjustable, clutch lever. Would it have killed them to put one similar to the brake lever on ?
And fender extender.
Other items being considered are aux lights (I ride a lot of unlit country roads), crashbars (somewhere to mount the lights if nothing else), and a side stand extender.
Anything I've missed...?
