Any body using 123D Circuits

This forum is huge (sub forum wise) .. so not sure if this is the right place for this question ..

New Arduino programmer here .. just came across 123D, and its the perfect UI ... The thing
that really bugs me is the small window they give you for " code editing "

First off .. is this program still supported ? Everything I see on it .. is really old.
and
Second ... is there any way around the small code editing window ?
