Agreed regarding the default tab completion. You might check out PSReadLine at some point - see https://github.com/lzybkr/PSReadLine. Its goal is to try to emulate readline except in PowerShell (this includes tab completion as well as emacs shortcut keys... vim shortcut keys are in the works AFAIK). It does require some additional configuration and it isn't installed by default, but I think it helps with this specific scenario quite a bit.
