I am blessed with some amazing team. The magnificent Cando just finished a new view for Activity Journal. It took me by surprise since all I did was suggest this view to be done, then he showed me what I thought is a mockup. Only it wasn't check it out on his blog. Basically its a graph that displays subject usage_count per day (item count/day) which is very useful tracking work stuff done each day.
The next iteration will include time spent on a document instead of the count. Of course this is powered by... you know its Zeitgeist :P
