I would love to try it out more than I have, but the fact that you have to enable Legacy is very disturbing.
Another issue I have with it is the lack of compatibility with other 3rd party apps, such as Gallery 2 and SMF or other forums.
Would love to have it if these issues could be fixed, hell, I'd even spring for the subscription (paid fee) as long as it was a one-time payment.
As is, I need to look elsewhere.
Nice job though! Wish I could use it. :)
