suggestions

is there any chance the fight display box (http://imgur.com/uHj134n) could be increased in size a little bit?

have to keep pressing up to check how much energy my opponent has, would be nice to not have to

for starters you could decrease the image size by holding control on your keyboard and scrolling down to zoom out or change your screen resolution to have a better fit.

Are you using the add-on to display energy left?

That's an odd screenshot. The battle box is supposed to extend down to the bottom of the visible area, so I'm not sure why yours isn't. Do you have any extensions active that may be modifying the webpage? As mentioned, you could also try playing around with the browser zoom to address your specific case.

i only use fishwicks extension and clay bangers. thats the way bots has always been for me

Can you try disabling the extensions, using incognito, or using a different browser to see if the problem is being caused by one of them?

I've noticed this website is extremely lacking in artwork. How about some cool robots on the main page, something like Mech Warrior.

ive tried all them and its still the same :)
