I think there should be a way to automatically set kits for all games on the server, Eggwars, Skywars, etc. There should be an option while picking a kit to set it as you default kit, and it will automatically be put on for ever game until you switch it. I couldn't tell you how many times I forget to pick a kit while waiting in the lobbies, so this would be a giant relief for me and probably many others.
