Hey!
I started playing bedrock more often last week and this is a serious thing that kinda annoys me. (I'm not that handy, I almost forget it all the time :c).
On Java you can just select a kit and it will save and automatically set that kit when you join a new match, this should definitely be on Bedrock as well!
Kits are very essential at the start of your game and it could be very annoying when you find out you forgot to choose your kit.
