I would suggest a button that will allow me to repeat or not the last troops used thus facilitate hurts to have to keep clicking forever same troop after closing the poop , the memory would be erased , assuming the barracks one put 10 gg and 5 archers , they reptiriam until I clear the button , the button can be independent or whole.
Another tip and a button to pause when sending speed , because sometimes we advance , the more we would like to pause and re-accelerate again later.
