Light theme, please.
I like the theme of the 1.2 client. It's clean, readable, nice.

I tried the new 2.0 client, and the dark theme makes my eyes water after 3 minutes, as I have to squint hard to be able to read anything. Since I could not find a way to switch to a light theme that doesn't make my eyes hurt, I switched back to the previous version, as this is a deal breaker for me.

So i just updated from 1.2 and i can't stand the dark theme. My eyes are terrible and the dark theme makes things difficult. I'll be rolling back until a light theme is implemented.
