Was just telling my friend I was a bit surprised at how rapidly consumer drones advanced in the late 2010's and have slowed down ever since. Seems like a lot of these features haven't really improved all that much in the past 5 years.
Most aspects have seen good improvements, in particular range, flight time and the camera. The Mini 4 Pro also has the 360° sensors that previously only were on the larger drones.
The Mini (2019) was a big step up compared to the Spark (2017) with merely a 2-axis gimbal and the Mini 2 (2020) brought very welcome range and camera improvements. I don't have first hand experience with anything more recent but it looks like both the range and the camera keep improving in those. The flight time, top speed and wind resistance are also increasing.
So i'm not sure what in particular you feel hasn't improved significantly.
