I think that the sell all feature from skyblock rank could be changed into something more useful as there is very little scenarios were it is actually useful (e.g. You have a multi mob farm but that's less efficient so if a player knew what they were doing, they wouldn't) and I have had skyblock rank for over 6 months now and I have never been able to use it properly, so my suggestion is that instead of a sell all feature, maybe like a "sell wand" of sorts as selling over 25 double chests of pork or gunpowder starts making both my hands ache and my controllers "a" button pushed down a bit. The sell wand could nerf how much coins you would get like a 0.5x multiplier or that it has durability that only regains after a set amount of time so people can't just only use it but I would think there should be a menu that pops up (maybe like the sell all one so it shows all the items sold) to prevent people from selling stuff they don't want to sell (for me, my diamonds to repair my tools).
