I concur about rechargeables - it doesn’t seem common for devices that take AA or AAA to have a battery gauge and it would be nice to be able to check the level on my rechargeables stock so I can know if I should top them off without needing to put each of them into the charger.
Lmao the first thing that came to mind was the “is there anyone else you forgot to ask” meme with apple in between the user and app developer.
