Coin/Gold Bug + Minion suggestion for better gameplay

id stand around and my minions wouldnt pick up coins even tho i had 0 coins and my miner wouldnt mine? also- you should be able to replace a minion's tool because i forgot to give one an axe and i was basically screwed. Another difficulty I had was one of my six minions getting caught on objects and lagging really badly. Also- I wish if you eaten enough mushrooms that you could identify edible ones..
