Layout One

Here is something exciting I've started last week! I'm still playing with layout, colours and custom-icons…

I'd love to hear your thoughts on this early stage design.

Attached the whole thing.

Cheers,

Some detailed info:
User can collapse/expand blocks in right column which closes the whole right column in case of all inner blocks are closed. So content section gets whole width with left nav.

Left nav has about 9 items for now, so I'm writing title (Calculators) in the content section to relate it better in case of active nav item will be too low.

Logo and most of content is dummy. I had to change…
