I would like to know how it is possible to reduce the number of items per line in the shop. Because actually it's 5 items per line and i would like to put only 3 and center them if it's possible.
In the future we'll remove the 5-per-line limitation and simply let page / browser width control the number of items per line.
Since designing that page in vBShop I've made improvements to the code it uses for other mods, which removes the necessity to add such a limitation. I'll back-port this code in a future vBShop version
