[Mod / Feature Request] Traders show needed item count

[user1679]

Requesting a mod / feature that shows the number of items needed for a mission (if you have one) next to the item for sale (if it is sold). To save performance, this number does not check your inventory for existing items.

When you have several missions that need various items delivered (fine meal, algae scrubber, etc.) it would be a great QOL addition if you could see that number in brackets next to the total for sale, if the trader has it. For example, if I have 4 missions that need 4x algae scrubber, 3x fine meal, 2x algae scrubber, 10x micro-gimbal and I talk to a trader that sells algae scrubbers and fine meals I'd see:

algae scrubber ........ 23 [6]
fine meal ....... 12 [3]
micro-gimbal ...... 7 [10]

The ..... is where the sliders would be for you to buy / sell the item.

This is also useful because if you already have, for example, 3 algae scrubbers but you quickly see you need 6 so you won't accidentally sell them when you get excited that they're selling for the green price of 75 credits.
