Sum Total of Hours Played

[crackalackintv]

I would like to have the sum total of hours played per month displayed in the GameActivtiy tab.

When I enable the "unify libraries" setting, the first chart with the total hours simply disappears. There should be an additional number of hours next to the "Total hours" chart header with the sum total of hours played across all libraries.

Similarly, it would be great if the Gantt view had a column that showed the sum total of hours per game for the selected timeframe.
