Thanks for waiting. Update version 6.0.2 is released earlier today.
We did a bit of engine tuning so that you will feel it is faster and more stable. It includes 13 bug fixes as well.
Oh yes, that annoying bug of search button is now fixed. Please check out our release note for details.
We know that there are more bugs to fix (thanks to your diligent reports!) and we are planning to do a big feast on that.
Until then, please enjoy the 6.0.2.
