Hi! I keep that in mind for some time already (exactly the storage tab thing). Unfortunately very small amount of players were interested in it, so this feature was removed from voting. However I feel like the time we should do it is closer with each release.
You could make it so that we can go into the settings. And press a button and allow free-floating items and have it set to the original way of picking up the items. And Have it so that we can have an inventory tab of each of the items as well. At the same time. All we have to do to change it back-and-forth. Press a button in the settings best of both worlds.
i get what you're saying, but its just weird that a quality of life adjustment is being treated like a full on feature that needs to be voted for first.
Imagine if minecraft never added the search feature when searching for blocks in creative mode because it didnt get voted for. (for a while you kinda just had to scroll and hope you could find the block at first glance)
But regardless i understand and i hope we do get it added one day when the Dev has the time to, they have done amazing work so far.
