The store becomes useless once all buildings and walls have been bought. Would it be possible to chose threw the store to upgrade buildings or walls. Say I wanted to upgrade a gold mine. Click on the gold mine in the store it would drop down a list of the mines you have and chose one to upgrade.
All I see is someone that is unwilling to spend at most 10 seconds looking for the correct building they want to upgrade. This is unnecessary and would just lag the game.
Is that not what alot of upgrades to the game are for to make it more user friendly? And as for the lag I do not believe it would cause much lag at all if any.
