[Closed] Derailleur hanger tools - and bad shifting

I found it started to matter more with 10 speed. Before that, I never needed to check alignment on a new hanger/frame, but then it started to matter. But these days that area of things appears more chunkily made than it used to be (through axles). Maybe it was/is mainly a thing with 10 sp and up with QR frames/hubs.

Has it had a new cable? inner and outer? that's the next place to try after straightening the hanger, remove potential faults in a systematic manner. It won't hurt to have a new one anyway.
