It would be nice to have the game set up where you can craft using items your retainers are holding without needing to go to your retainers to get the items. Elder Scrolls Online has a system like this, any items held in your bank (because they don't use retainers) can be used to craft without needing to go to your bank to withdraw the items you want to use. Too many times I loose track of what retainer has what times, so I just buy from the market board and resell what I don't use when I want to craft. It would be very convenient and user friendly to have items available for crafting without needing to go to a retainer to get them first.
