Sorry for the 2 in 1
As properly managing storage seems to be the crux of a functioning town, having the option to untick all boxes would be great. Either untick all, or at least untick by category. Since at this point if we want a storage facility to only accept 2 materials we would have to go and untick every other material one by one.
Second, It would be nice if the trader would leave a notification when he arrives and shortly before they leave (the leave part is not that important). It is too important to have them be missed just because you were wrangling your cows somewhere off in the distance.
