1.6 update

[Garkin]

New constant "bonusLabel = 0" is just variable leaking to global. Tha same goes for new table "trainData":

function ZO_Stable_Gamepad:SetupEntry(control, data, selected, selectedDuringRebuild, enabled, activated)
    data.isSkillTrainable = data.data.isSkillTrainable
    ZO_SharedGamepadEntry_OnSetup(control, data, selected, selectedDuringRebuild, enabled, activated)
 
    trainData = data.data
    ZO_StableTrainingRow_Setup(control, trainData.trainingType)
    bonusLabel = trainData.bonus
    if trainData.trainingType == RIDING_TRAIN_SPEED then
        bonusLabel = zo_strformat(SI_MOUNT_ATTRIBUTE_SPEED_FORMAT, trainData.bonus)
    end
    control.value:SetText(bonusLabel)
    ZO_StatusBar_SmoothTransition(control.bar, trainData.bonus, trainData.maxBonus, FORCE_VALUE)
end

Tables "items" and "usedFilterTypes" are leaking from here:

local function GetBuyItems()
 
    items = {}
    usedFilterTypes = {}
 
    items, usedFilterTypes = ZO_StoreManager_GetStoreItems()
 
    --- Gamepad versions have extra data / differently named values in templates
    for i, itemData in ipairs(items) do
        itemData.pressedIcon = itemData.icon
        itemData.stackCount = itemData.stack
        itemData.sellPrice = itemData.price
        if itemData.sellPrice == 0 then
            itemData.sellPrice = itemData.stackBuyPriceCurrency1
        end
        itemData.selectedNameColor = ZO_SELECTED_TEXT
        itemData.unselectedNameColor = ZO_DISABLED_TEXT
        itemData.name = zo_strformat(SI_TOOLTIP_ITEM_NAME, itemData.name)
 
        local itemLink = GetStoreItemLink(itemData.slotIndex)
 
        itemData.itemType = GetItemLinkItemType(itemLink)
        itemData.equipType = GetItemLinkEquipType(itemLink)
 
        local IS_STORE_ITEM = true
        itemData.storeGroup = GetItemStoreGroup(itemData, IS_STORE_ITEM, itemLink)
        itemData.bestGamepadItemCategoryName = GetBestItemCategoryDescription(itemData)
    end
 
    return items
end

I'm not sure about table "color", I have it in my globals dump too, but I didn't find it in source code.
