Mood categories

Hey I'm loving Moodlog! But my proclivity to overspecification is causing my pie chart to look pretty chaotic -- it's a pie with an awful lot of slices. The colors are helping a lot to making sense of it (was this intentional?), but maybe it'd make sense to define mood classes that moods could belong to? Even something as broad as "positive/negative/neutral" would be a fun viz. I imagine these'd have to be user-defined, of course :)

Anyway, thanks!
