Hi, here are some ideas to improve UX, i think they are quite common sense and common practice in most asset programs.

Search in KITS - I wanna be able to write a few letters of the kit and it will filter, there is more and more kits, which is awesome, but going through them is troublesome.

Kits - arrow to go back to overview of the kits to same place i was before opening the kit.

F.E i was on military outpost kit- ok my model wasnt there, lets go back, and scroll down - i cant i have to go back to all kits and scroll from start, minor inconvenience, but its a common practice just to be able to go back and continue.

In model - hyperlinks for kits - f.e. i find a model that i like (maybe there is more like that in the kit), there is written which kits its from, why cant i just click on the Kits name and it will bring me to the kit?
