When performing a clone, a 'working' type progress bar is shown that simply indicates that a process is being performed. This gives no indication of how long the process will take or at what stage the process is. The message window below it also provides no current status messages except from the starting and ending messages.

I have several large projects to clone and they take a long time (hours), I have no way of knowing if the process is simply taking a long time or if it has failed. For this reason I used TortoiseGIT because this has a full progress bar and a constantly updated message window describing the current operation. It would be great if SourceTree had a similar progress bar when doing a clone.
