Where is ggg on putting a tab in for tablets to purchase

Ggg you see we have points that want to use. Tablets need a stash tab even if refunded if you change tablets or switched to new currency.

Ggg you have options we need this tab.we will pay you money for the tab let's do it

I'm quite confident saying that the reason why there isnt a tablet stash tab to purchase is that GGG is not yet sure what to do with tablets in the endgame. We are going to get massive endgame changes in next league (patch 0.5) and if precursor tablets are still a thing we most likely see a tablet stash tab on shop aswell.
