Here my point why does a Miner need a Fuel, Decontamination, Recon, Hatch Breaker, Repair and Research. I don't see the use of other limpets. Depending on what your doing depends on what you limpets you need.
I've found that not all types of limpet controllers are not found at all stations. When mining, I used to only use collectors. With the introduction of prospectors I now need two controllers, so two slots are taken up. If I only have two type-2 slots that's one controller for each of those two slots instead of squeezing each of those "1" type controllers into each plug instead of sticking them both into one module slot, i.e., split them.
The other thread concerning this issue is the "One controller to rule them all" idea which I would gladly support. It's getting to the point where there are so many things you can do with them that it boggles the mind. Yet how often do regular players bring along fuel limpets? How many wish we HAD brought them when finding a vessel in distress that may need both repair and refuel limpets? How much space you got in your ship again?
You just cannot plan ahead for ALL possible uses of limpets and bring all the possible controllers for each of them. Things can happen you just can't plan for all the time. I believe there are eight controllers now, right? Squeeze all of them into an anaconda or Type 10 and go looking for things to use them all on.
Just one controller with a setting to do this, that, or the other thing. The limpets are universal; they'll do whatever your controller will tell them to do. I don't see the need to bring eight other boxes when a simple dial on the box can do the same thing.
ONE CONTROLLER TO RULE THEM ALL
