I believe there is a better way to do the Lazarus rack interactions so there isn't so much inventory interface jank.
First, to do away with all the micromanagement with food and memories, place a box somewhere in the Laz complex with unlimited inventory only for those items. This box connects to...
Second, a new station(replacing the PECO terminal) near the racks, a new UI (similar to the current rack UI) that updates based on what is in the box mentioned above. It would include a search function that can filter for item names, traits, etc with each item having the standard plus/minus interface (ex Bowling Ball - [1] +). Importantly, you do not require a human seed inserted to be able to use this. You can just go in there whenever you'd like and play around with human builds at your leisure because...
Third, the humans you build in this interface can be saved and loaded into the Laz racks when you insert a seed. If you load a build that you don't have the items for, you get informed of this but it does load all the items you do have and thus lets you alter the build in real time to make changes.
There's a world in which the current interaction with the racks is completely removed and streamlined to this new centralized station. Letting the player load builds to racks directly from this new interface to specific racks (Load to Rack One, etc)
