I've been using the group by namespace feature to allow me to quickly get to the items I'm interested in via the class list. But ...
When I find and expand the child namespace I'm interested in then sure enough I see the classes I want. Now I select one of them and I briefly see the class reference explorer and instance list for the item before the namespace field next to the "Group by namespace" checkbox is cleared and the view jumps to the top of the class list. This happens every time and it starts out being a little annoying, but quickly grows in intensity.
I can scroll down the list to find the item I want - it is still selected, in the sense that the icons are still shown for that item and I can now select them, but it quickly becomes a pain to do this all the time.
If I type the full namespace, which has the form NSa.NSb.NSc, then the only change is that I can re-select that namespace and go straight back to the class I'm interested in. But (again with the buts), in our case NSa.NSb has about 30 child namespaces and I'm reluctant to clutter up the namespace selector with them and it only makes it quicker to recover from the problem. If I select another class the view jumps again making browsing through the list very annoying.
I wouldn't be at all surprised to find out that there is a good reason for this behaviour, but I can't figure it out. Is it by design or is a bug?
As a supplementary question - is there any way to remove a mis-typed namespace from the namespace selector without going to the registry and editing the find key?
