Klyotan,
I'll answer your question directly:
I read your links with interest, and I have never run into any of the issues you post about here (including the takelane issue you so thoughtfully provided a video of.) The reason I haven't for most of them is probably because my workflow is different from yours, so I haven't run into those specific defects or I haven't set up the conditions for them to show their ugly little faces, but I do sympathize with your frustration. I know you don't want to hear about suggested alterations to your workflow, so I'll move right along here.
You're entitled to feel whatever you want, and you're entitled to express any opinion or make any assertion you feel like making here. I fully support this exercise in disgruntlement exposition, and I completely understand if you decide to pack Sonar away and move along to another product. We do what we gotta do to make things work.
On the other hand, no one is required to agree with you or anybody else here, and I find it a bit humorous that so many folks post things and then get upset when people challenge their assertions.
As a software developer, you're no doubt aware of how bug reports flow through organizations and how they decide to fix things. If you're a corporate developer, reporting status to your customer is an essential part of keeping the business running. As a commercial product developer where customers may number in the tens or hundreds of thousands, or even millions (in the case of companies like Apple, Google and Microsoft) closing the feedback loop is incredibly difficult. Nobody likes letting that kind of opportunity for customer communication go.
As for the issues I do experience, I elect to read the release notes and check to see if the most impactful issues are still there. I don't want to tell you how to manage that process, but if you do that, you don't need to post questions like the one you posed here. Just skip to the part where you create a fun Cakewalk-bashing-rage-quit thread.
[Update: This last comment is supposed to be humorous and does not necessarily reflect my opinion of actual persons, either alive or dead.] I sincerely hope you find something that works well for you!
