Since Murky is a Mac centric front-end, it would be nice if there was an easy way to open up Xcode projects from the Murky interface. This could be something as simple as a double-click or contextual menu item when clicking on an Xcode project in the browser pane. Though I understand this might be a little haphazard since the pane is intended for revision history, so a better idea is probably needed.
But I find that I usually launch Murky and my specific hg project, then have to reveal in Finder, and then find my Xcode project and double-click it. It seems this workflow could be optimized significantly.
