ability to upgrade a row of walls at a time
when you upgrade to another town hall you get a pile of new walls. players who have the cash to upgrade walls to much higher than level 3 or 4 know what its like upgrading 50 walls, one at a time 5 or 6 different times each. the ability to upgrade a select row of walls would be outstanding. even the ability to upgrade a single wall more than one level, say "upgrade to level 5" or something to that effect. i know this idea is not there so tell me what you guys think!:D
