Tip: You can provide bug reports or suggestions (new features / improvements) through the Microsoft Connect channel:
PowerShell – Microsoft Connect
You can see the bugs or suggestions reports and you can also vote them to prioritize so the PowerShell team can see what are the most asked / needed by the community.
PowerShell – Feedback Center
There are different available filters : by latest items, most voted items, active, resolve and closed. An advanced search is also there.
An example of suggestion submitted, the status is active with a vote +1.
The community can also comment (maybe they found a solution/workaround or they have the same issue and want to provide more detaiks, etc.)
