It's worth noting that around 20 of the 60 or so issues that the OP raised have now been resolved, including 6 of the 9 priority 1 bugs. That's in just over two months. Of course most of those fixes won't arrive until 6.0 goes live, but the key point is that you'll accomplish a lot more by filing bugs or voting for existing bugs than by simply complaining.
Votes are important because they raise the visibility of an issue. Just commenting on a bug is not sufficient, you need to vote for it.
- When you file a bug, vote for it. If you think it's important post a link to the entry in bugzilla here and ask people to vote.
- If a bug you file is marked as a duplicate, be sure to vote for the original issue.
- When you see a bug that you would like resolved, vote for it. Just commenting in the bug report is not sufficient.
