Sorry for my English, I had to use a translator.
At the moment, working with several inventory items at the same time is a complete pain, for example, during construction, you need to constantly open a backpack or a bag with materials, and it is also extremely inconvenient to transfer things from one inventory to another, especially when working with nested inventory (for example, with an emergency bag and backpack). When performing many other actions, significant difficulties also arise.
I suggest keeping the system with cells, as it is quite convenient and interesting in gameplay, but adding the ability to open multiple inventories at the same time. In my opinion, this will improve the quality of gameplay for all players, regardless of their skill level and the goals they are trying to achieve while playing space station 14, at least reducing the unnecessary time spent opening other inventory.
