The mod uses a single GUI window that is created once on initialisation, in this step the number of squares
that is generated is based on the longest inserter that can be found in the entity prototypes of the game.
When opening an inserter, this window is just being updated.
Creating this window dynamically would require me to do a lot of code changes and testing, time im not willing to spend right now.
Im sorry to disappoint you, this mod was never intended to work with inserters with >3 tiles range and im not going to add support
for hacky meme mods like Renai Transportation.
