Are there any alternate RDP Clients for Mac

Instead of "Microsoft Remote Desktop." The reason I'm asking is that for whatever reason, Microsoft's RDP client for Mac does not allow you to organize your saved connections into folders or categories. So if you have more than half a dozen or so saved RDP connections, it can be difficult to find the one you want.

This isn't a huge deal, but it would make things a lot easier if there was a decent alternative to Microsoft's RDP client.
