These are generally small things but things that would be most prefered for previewing item builds.

HUD Stat Display: Something like on the PC version that shows your overall stats (Basic Attack Damage, Movement Speed, Etc.) without having to constantly open the shop and manually check on it possibly Right of the Relic/Potions Box, Below the Item Bar, or Left of the Abilities Box.

Item Builder Stacking Item Preview: It's not easy to compare the stats from the menus when comparing stacking items like Warlocks, Book of Thoth, Transcendence, or Devourer's Gauntlet without the ability to slide the stacks to see the late game potential, could update it like how you can preview stacked potions.

Nothing really game changing, just feeling this would make certain situations easier to manage.
