I have a problem that a good chunk of people also have... I'm a horder of the worst kind and my inventory is an absolute mess, because of it. Been playing for 8 years. My retainers are so messy that they have multiple stacks of items split amongst 3 or 4 of them at one given time and the loading process to go in and out of retainers is just not fun.

What I would love... LOVE... is a Retainer Sort All button that moves all Retainer inventory around to Sort EVERYTHING. Merging stacks into one and all the normal things that Sort does, but as if it's doing so with an Inventory of 1000 rather than individual sets of 175... if that makes sense... that way all the gear amongst my 7 retainers would all go to 1 Retainer automatically through Sort... since gear is the first thing to get sorted.

So that's suggestion number one that would be the biggest help...

Probably an even bigger help though... for the love of God and all that is Holy... please let us use our Retainer's inventory if we are 50 yalms from a damned summoning bell. We can pull up a recipe tree and see, "oh hey, I have all that! But now I have to hunt down all that from 5 different retainers." Please.

You could even make this a housing item... a Crafter's work bench of some sort that allows to do this from the safety of your House, which would make the housing demand go up even more, buuuut... the important part isn't HOW something like this is implemented... its that something like this gets implemented in the first place.

These are 2 major things that could bring so much quality of life to our screaming incentories... and also free up some server processes by having us going into our retainers over and over again.
