When exploring for a lot of one particular item from a certain location, I find I'm constantly having to go to the location's page to sell all capped items before continuing to explore that location.
I would be cool to see a "Sell All Unlocked Items" button similar to the button at fishing locations but have it specific to the location you are currently exploring. The function would sell all items that can be found at that location that aren't marked locked regardless of the item count.
