It takes way too long to go from one retainer to another. They each need to do their hello/goodbye animation, plus it's like several clicks.

In the retainer menu, the item menu, and the venture menu, there should be an up/down arrow that brings you to the next retainer on the list skipping animation/retainer talk.

That way, it won't get so tedious cycling through 8 retainers and their ventures, or trying to gather materials from multiple retainers for crafting.

Either that or add a button that allow us to collect and resend ventures for all retainers at once.
