TL;DR: new UI pretty but less functional.
This "2.0" version of Happiness is pleasing to the eye. However, the Analysis capability is generally less capable than the old version. Also, the Analysis screen is somewhat confusing as it now encompasses three different screens that I can left/right drag to.
The "journal" feature is good but:
(1) let me distinguish between tags and free text on the journal entry.
(2) I should be able to edit a journal entry after the fact.
