One major problem in LIF:YO is the lack of a scroll bar and/or grid system on the inventories. This leads to many items overlapping and hiding eachother... Many complaints about this can be found on forums around the internet, however the devs don't seem to care.
The game really needs a Grid system and Scroll bar to allow items to be found without needing to move every item out of hundreds around your warehouse.... (Needle in a haystack literally when looking for Nails)
