We have an active beta testing program and every update is tested before it is released. We do not yet have the capability of testing every feature on every possible platform under every possible condition. I wish there was a simple solution to solve every problem at once, but that doesn't exist.
We no longer announce our future development roadmap for exactly the reason you are complaining about. A lot of features we thought would be easy had more problems then we initially anticipated and have taken significantly more resources to complete. We are still working on all the features that are coming soon and have plans for other enhancements that will fix some of the limitations with the current version, but we don't announce new features or potential dates anymore because sticking to the timelines has proven beyond our control and available resources.
I'm sorry the latest update is creating issues for you. Being specific about your problems would go alot futher to get them fixed then threatening to sue us though.
