Sure it's infrequent, but that's a poor excuse for needlessly complex UI. When you *do* set them up, you're likely to be setting several up at the same time, so the issue presents itself in a large, if short-lived way at that point. Further, the issue extends to other 'tools' like berries, and to switching between the chainsaw and stun-gun a little later on which you may well end up having to do frequently when exploring and clearing forrested areas.
Manually emptying the miner is, as I see it, the intended handicap for its low tech level. I wouldn't mind some additional requirement like having to charge it somehow (to balance against the mk1s needing a power line) but the deployment UI could use some work.
