Hi Michael,Today is my lucky day. Someone is looking at concrete issues with Cloud Console. I will provide you with any information you need. You can't imagine how much pain I had with it.
Re 1. To be fair for last two days it seems to be working. But I had problems opening task queue when it had lots of tasks in it and it was active.
Re2. a) I go to Dashboard and here is what coming:

2b) GIF speaks better that 1000 pictures. Here is a gif showing my experience with QueryTool:

What can we see from the gif above:
i) apart from being very,very slow, it gives error messages even without me selecting anything (which is very annoying)
ii) then I try to enter namespace and kind, and it keeps giving exceptions (seems it is trying to be smart and lookup while i am typing, but I would rather it wait till i finish typing)
iii) Here is the biggest issue. Once I typed namespace and kind and it tells me there is no such entity, i have to clear kind field and paste it again for me to finally see entity
iv) no way to see list of namespaces
v) no way to see list of kinds
It seems this query tool was not properly tested with namespaces. I hope you can see, it is a pain to use. I even don't mention the improvements to the core functionality of the tool, just to get the basics working that will be great in itself.
Re 3 &4: It's not intermittent, just doesn't work for one particular project (which by the way is the one I care much about). This is what I see:

I hope this helps. Let me know if you need any more information.
Thanks .
