Keep Crash on Startup
Seems good but I cannot use it. Keep crashing on startup (on both of my Macs, OS X 10.9 and 10.11 beta).
Already report to tech support and waiting.
UPDATED: It seems to be some in-compatibility with input methods other than English. The tech support gave me a test version of 3.0.1 which does fix this issue. Hope the App Store version go live soon.
