This fully does not warrant an Installer package. It's one item; it should just be drag-and-drop.

Supposedly supports multiple connections, but try as I might, I can't get any more than one open at a time; not by the connect dialog, and not by the "open connection file" option. This also seems to be confirmed by the application automatically quitting when I close the last RDC window.

The contents of the Preferences panel seems inappropriate. Preferences should be for the whole application, and it currently contains the settings for a particular connection; eg: username/password, things to launch at login, display and keyboard settings - none of those should be application-wide (and if they're not, they don't belong in Preferences).

The GUI is kind of glitchy; specifying a fully qualified domain name results in the green badge on the Dock icon not fitting (eg: connecting to server1.blah.microsoft.com, the badge icon says "icrosoft.com"). If they're really determined to show the server name in the Dock, it should show the host part of the name (eg: server1 for server1.blah.microsoft.com).

Other UI issues include the window shrinking down to a tiny postage-stamp sized window down in the bottom left corner of my screen when I clicked the Zoom button. I would have thought the dynamic resizing thing would cause the window and the Windows desktop to resize to fill my screen. Apparently not.

It seems to completely hang quite easily. Seems to be a choice between hanging periodically in the 2.0b, or crashing periodically in 1.0.3. Six of one, half a dozen of the other...

I'm glad they're working on this, but at the moment it's not very compelling. It would be nice if they're going to release a preview version, if it had the features they're touting (ie: multiple simultaneous connects). I understand that the feature might not be ready yet, but don't say it's there when it's not (or say it's "coming soon").
