2. Make this number bigger (x2) and with a contrasting background (and character damage numbers too).
3. Make this button pressable with mouse.
4. Increase space between icon row (x1.5 - x2).
5. Add any possibility for use Attack! skill and Shoot skill with keyboard. Usual I use 1 and 2 for it. But they changed in battle.

I have some problems with vision and color perception. I think not only me.
I hope you pay attention to the item 1 and 2.
Thanks.
Update.
6. Please add combat log with all this number in system chat.
