When selecting troops (or market resources) you have a button on the right to select "all" of a troop or resource. But, if I want to go back to zero ie; don't want any of that resource I have to use the slider. I would prefer to have a button on the left as well zeroing out my selection. Also, coordinates for finding a tribe, or even entering market numbers etc. When you go into the box to enter the amount or number the field should be blank, not have the number zero in it, which then causing you to highlight the zero, or backspace to get rid of it etc. Bottom-line, when the field is selected, the value should be blank/null... ready for entry.
