I get used to interface very quickly,maybe I am using poloniex since begining,
orderbooks are below chart with two different tables side by side

but you should consider another layout options for leonardo,

like cryptowat.ch, bitcoinwisdom view.
Order books, on the right side of the chart as same column view,

sometimes layout difference is more important than functionality,
as the main first-sight impression, adaptation etc...

My main disturbance is the margin and funds view on top, I am using a lot of pair windows at the same time,
When the decimal point for funds are 6 or more digits and it steals all the area from pair window tabs,
I will be more happy if top side is reserved only for pair window tabs,
another compact view for margin and fund tables elsewhere,

I want to learn the other users opinions about that
if I am the only one who is getting crazy of that thin arrows moving the pair window tabs

Best Regards
