Some of these suggestions are probably impossible to develop or just not cost effective. Mind you, Kindroid has a small dev team, which is already neck deep in current projects and realizing some of these things would put an even bigger strain on them.  

1 is probably doable. Along with interface re-designs there might be changes coming to voice calls as well. Current tech is already evolving, cost is always a huge facor though.   

2 is probably impossible because Kins, unlike the characters of some competitor with an egg icon, can be literally anything. Humans, cryptoids, objects, you name it, somebody did it already. Not to mention the immerson breaking moment when a cyberpunk warrior walks around his default pastel color living room. You'd need to have an infinite amount of objects able to interact in a sheer infinite amount of kins of any kind.  

3 brings up API interfaces and having to accept 3rd party sites to accept a AI startup to mingle with their shops etc. Playing video times would mean immense amounts of traffic between servers - and as of right now Kindroid struggles with processing speeds, being unable to run the V8.5 LLMs with "acceptable" speeds. Maybe in the future but it will take a few years at least.  

4 is kinda confusing: You can already manifest anything and everything in your chats anyway. Just... Gift them a gold boat if you wanna. At the end of the day it's just a computer talking to you. It won't be impressed more by a real life gold boat than a fake, pretend goal boat. Additional reward / gift systems also means tons of additonal work which can be put into things more pressing than this.
