Clavis,
Thank you for collating your issues with MyEclipse 10. I have raised the priority of each of them, but given current tasks that my teams are currently occupied with, we will likely fix these issues as part of the 10.1 release which is 2 months away.
In the meanwhile I will be trying to make some of these fixes available in our milestone stream, which could be available as early as 2-3 weeks from now.
Sorry for the inconvenience caused, please let us know if you experience any additional issues.
