Mouse Tweeker alloy to Click + Drag to place in storgage Multiple Stack really fast, It work on pretty mutch every stoprage component (like chests), but It doesn't work at all with Ender Utilities Machines and storages... I think you should really look for that because Mouse Tweaker is in pretty mucth every modpack and it really really usefull!! Other really usefull thing is the Scroll on a item stack to move to storage or to your inventory, same, doesn't work at all with Ender Storage...

I have no idea what and how Mouse Tweaks is doing so that it doesn't work at all in my GUIs, but I doubt there is anything I could do about that on my side without completely rewriting all of my inventory and GUI code to use the vanilla IInventory instead(?) And that's not going to happen. But if anyone happens to know what exactly it is that breaks it, and if there is an easy fix I could do, then yeah I can do that.

However, you could replace Mouse Tweaks with Item Scroller, which works just fine in all of the Ender Utilities inventories as well: https://streamable.com/9ubtd
