Hello,
When you want to change equipment, you go to Pilot Profile → Fleet → Loadout where you can change equipment for your Flagship.
I want to suggest Loadout button to be added in Fly mission preparation for quick weapon / Equipment swap. This will skip extra steps and save few clicks when you want to use same spacecraft but change weapon according to mission you are about to fly.
Here is a MS paint edited image of suggestion:
I think this will be a small Quality of Life change.
Tell your thoughts on this.
Thank you.
