spell/barracks build order, cancelling spells, end battle button

Hello,

I don't know if this frustrates anyone else, but it sure frustrates me.

Spells should not stack when creating them. Say if you like using 3 rages and 1 lightning, I'm sick of starting a battle with 1/2 rage whilst another is in process, I finish my raid and want to top up my rages again, it pushes ahead of my lightning which has yet to be created.. I never get to use lightning unless I don't spend my gold, log on when all rages are completely finished or used up then create when lightning starts.. Make the purchasing go in order, not stacking..
I'd say the same about barracks but I think that will be too complex to design.. It will help donations with the clan not having to cancel their build to build someone a wizard, if you expect someone to req a wizard when you make 200 arch, it would be great to be able to make 10 arch in each rax, 1 wizard, then a further 40 after it..

Back to spells.. losing 50% of the cost is too much.. reduce it to 20% or none at all. The amount of times I get in the rhythm of picking troops I accidently buy a jump spell or heal spell when I am farming or w/e annoys me. Yes it is my fault, but it's my resources which I work hard on getting.

While countdown begins and your scoping out the opponents base, it would be good if end battle confirmed your request like the surrender option does, opposed to going straight back to home.. again, the amount of times I find a great raid and drop an archer on the end battle button baffles me (lol)

That's my 2 cents for now :)
GJ thus far.
