Why keep suggesting spring trap upgrades?
When I push the builder's info button it always suggest upgrading spring traps. I have upgraded by spring traps once so they will now toss 16 storage units worth of troops but I don't see the benefit in upgrading any more but the builder info keeps suggesting upgrading the traps. I would prefer if the most expensive upgrades were suggested, that may be a wall over a spring trap. Also, don't list the same item twice unless there is absolutely nothing left to upgrade. I my case I usually have spring traps listed twice. That doesn't show me the option to upgrade a wall.
I do like the feature where I can see when my builders will be done. For suggestions I think it would be nice to alternate between the cost and when the builder would be do if that upgrade is started. It would help plan the use of builders. I find it best if the builders don't all get done a the same time and then wait as I start the builders on new upgrades one by one.
