I would really like some additions to stream line the melee screen for battles. I would like all these to be available from the melee screen.
Have the ability to turn off weapon and/or death animations to speed up battles.
Have a button/keystroke for the current unit to take 1 turn on it's own.
Show owned shards so we know where our strength areas are.
When giving spell damage estimates, give actual range of values in addition to how it is calculated. That is for instance instead of showing a damage as 8 (+4 per fire shard), do the actual math with bonuses and number of shards taken into account and give the range of possible outcomes.
Thanks,

Some sort of additional animation adjustment I agree with. I forget the spell (Titan's breath or some such). I used this against a large army, and it takes....a while for the enemy to get back up. Mostly I don't mind...but it was a battle were I was severely out matched and I had to use all of my mana to get though it...a lot of breathing 
Single AI turn. Not too sure about this, I've never encountered the circumstance where I am going to entrust a turn to the AI but not the battle, so I'm not too clear how useful this is.
Shards - Tooltips - I don't think the shards are that important as much as the tooltips but I can see the reasoning. If you have a 'fire mage' and a defensive 'earth mage' and it's one or the other's turn and you want to know whether to spend the mana on this guy or is your mana better used on your other mage. Thing is I don't think it's that crucial once you learn to remember where your shard makeup is. I do think the tooltips should show a more accurate damage assessment (inclusion of targets defenses isn't required to me, just a baseline...I'll figure out if the troll is going to take more or less damage than the tool-tip indicates.)
Edit - autoresolve sans mana - I kinda feel the same way. I'd hate to have my pack of casters blast away an army of spiders when they are armored to the teeth. But I have to say, so far, I haven't seen this happen. I've watched too, because there was times when I needed to teleport or needed my pool over 100 for defending against a large army and have cringed while hitting auto-resolve...but the mana always stayed the same.
