When I’m trading in the Diplomatic screen and I want to trade Blue Cap Mushrooms, I don’t have a listing of the current numbers I have, nor do I know how many my ally has. When I was working on monopolizing a commodity, I had to go to the window with all of the planets so many times because I would forget the number that was currently available.



Would it be possible to have something that says you have seven of these so you can trade four?

I fully second this! In one game I accidentally traded away all my Quadrinix causing my terraformings to high level planet classes to go to 999 turns blocking the build queues without notifying me. I noticed this many turns later by accident.



There is another thread addressing this problem: http://forums.amplitude-studios.com/showthread.php?6339-no-way-to-tell-number-of-resources-available-when-trading

Similar to /#/endless-space/forum/28-game-design/thread/12005-resource-trade-feedback-usability-improvement even if the original title of that thread was ill chosen.

This thread has been linked to the former and is moved to the archives.
