Deleted stream still appears in P4V Depot Tree:
The solution is clear, it is just will be very useful if deleted (task) streams can appear with some special mark which flags the user that the stream task is deleted, and that the relevant options like "work in this stream" will be removed/greyed-out from right click - right now it shows errors on deleted task streams.
Another request, even more important, is to add an option to filter depots - filter deleted streams - normally you don't want to see them.
Also add an option to filter deleted (task) streams from file revision graph, and save/manage these filters, many deleted task streams makes the graph hard to understand.
As task stream is intended to be deleted, P4V is very missing these options.
