Putting things in order...

I would like to see the ability to set your preference for retraining your troops. In the event you want your shooters or raiders up first this would give you the option to push Howies & Supply Trucks to the back of the line (or however you would like).
This affects me mostly when I'm casually playing and after donating 3 or 4 Howies they clog up the front of my barracks slowing down the raiders & infantry.
I really like that they did eventually 'balance' the load between barracks. This would be a welcome additional feature letting player optimize their barracks.

I like it, and I want it per barracks. If I am raiding, I want one barracks making raiders, one infantry, and one shooters.

The only hiccup I see with this is that you might wind up with fewer raiders then you'd like due to infantry and shooters training so much faster.

I like this idea, give each troop type a priority number. AND, to take this idea a little further: in the same way we have 3 different base setups saved, why can't we have 3 army combos saved? People can easily toggle between their raiding combo, or their mixed combo, or their HT combo, etc, etc.
I know on those occasions when I crash I would really like to just hit a combo button instead of going to each barrack and train each troop one-by-one.

Dangit! Who said anything about taking things one step further!? lol...

I like THIS idea. I believe various other games, like Boom Beach and Clash of Clans do the same thing. You are given the ability to name each troop setup and then, at a later date, select from the setups you have already chosen and named.
