What things are you missing from old Android versions?

I had a realisation recently that I haven't had the requirement to root and customise my FP4. I don't have a terminal app and I've probably forgotten the majority of the ADB commands I used to use!

Maybe I'm just being assimilated into the Google/android eco-system.

A long bar.

The handle of my trolley jack fits nicely over my ratchet handle.

Also get a torque wrench. The sump plug torque always feels surprisingly low.
