All time got this advice. What need to have 180 slots??
The Old Man
all visible slots/windows must be filled before a new line of slots appears.
I suggest you use something like original magnetic ore (omo), tiger totems or logs or something that stacks to 100+...
separate them into "stacks" of 1
ctrl+ Left click each omo or totem filling every slot, until you see all lines of storage.
keep lesser or unused items in that lowest/last line of windows, that way you will always see all lines of storage.
