So I'm using my own version of Alza's aBags. For a while I've been trying to make it automatically update when a new/bigger bag is equipped, but it requires a Reload UI first. This is because the script that reskins bags is only ran once, to save CPU:

local firstopened = 1

...

local ReanchorButtons = function()
	if(firstopened==1) then
		for f = 1, CheckSlots() do
			con = "ContainerFrame"..f
			_G[con]:EnableMouse(false)
			_G[con.."CloseButton"]:Hide()
			_G[con.."PortraitButton"]:EnableMouse(false)

			for i = 1, 7 do
				select(i, _G[con]:GetRegions()):SetAlpha(0)
			end

			for i = GetContainerNumSlots(f-1), 1, -1  do
				bu = _G[con.."Item"..i]
				bu:SetFrameStrata("HIGH")
				tinsert(buttons, bu)
				_G[con.."Item"..i.."Count"]:SetFont(C.media.font, 8, "OUTLINEMONOCHROME")
				_G[con.."Item"..i.."Count"]:ClearAllPoints()
				_G[con.."Item"..i.."Count"]:SetPoint("TOP", bu, 0, -2)
				_G[con.."Item"..i.."IconTexture"]:SetTexCoord(.1,.9,.1,.9)
				_G[con.."Item"..i.."IconQuestTexture"]:SetTexture(C.media.questborder)
				_G[con.."Item"..i.."IconQuestTexture"]:SetVertexColor(1, 0, 0)
				_G[con.."Item"..i.."IconQuestTexture"]:SetTexCoord(0.05, .955, 0.05, .965)
				_G[con.."Item"..i.."IconQuestTexture"].SetTexture = F.dummy
			end
		end
		MoveButtons(buttons, holder, GetColumns())
		firstopened = 0
	end
	holder:Show()
end

...

for i = 1, 5 do
	hooksecurefunc(_G["ContainerFrame"..i], "Show", ReanchorButtons)
	...
end

(CheckSlots is a function that returns the number of bags)

What would be a good way to make sure that it's also ran again when a new bag is equipped?
