we are may-be diverging a bit from the original subject ? but yes I've never used dble-click to select all traders because I usually never trade only one resource and that is the rare case where it is usefull. In fact, before the A16 changes, I nearly never changed the resources assigned to my traders because it was really not convenient. But I agree that for people trading only one resource at a time, and changing it frequently, the new system implies more clicks ! may-be we can try and improve the present trade window (waiting for a full gui review) using keys : for example, when we ctrl-click on one resource, it will be put to 100%. We could also change the step to be 10% instead of the 5% which is may-be not really needed.
