A 'So Far' Query

[LordNightwinter]

So as someone who backed the Kickstarter but hasn't been in on the beta I haven't had a decent look at the program or its features (Edit to clarify; Haven't been paying attention is a better assessment of the situation, lol). So my question to the burgeoning community is this: Those of you that have been testing/using it, how useful has it been at the table? What are the best/worst points? Any lessons learned for using it?
