Im getting to the point where i can ask this question. For the shop would you all like to keep the menu we have and just have it scroll or have a menu that takes up a good size on the screen and have sections for each type of item?
As just general advice, I'd suggest having categories. And the ability to sort by price, Health, Or damage.
So for example, A weapons tab, A throwables tab, A buildables tab, A personal use tab, Etc.
I think that is a better way to go about things in the long run because you will eventually need to have a system like this, And if you do it later rather than sooner when there are many items in the game, It will take a lot longer to sort your huge item library into the tabs.
So just do it now. Save yourself the future effort.
