The solution's interface is complicated to use for a new programmer. It needs to be more accessible.

For everyday use, I am more comfortable using the command line interface, rather than using SourceTree.

The way our system works for software deployment, having to install this product is inconvenient.

There is a cost for using this product, whereas the command line is at no charge.

The product's UI needs improvement.

I have had a food experience with Atlassian SourceTree but it might not be for everyone.

I think the console can be improved, to allow more shortcuts (for example- supporting dragging a file from the Working Copy to the console ).
Another small improvement I can thick about: allow creating folders to divide the branches and stashes, this is a very simple change that will make things clear.

The UI can be improved because it is not always so easy to find the functionality you are looking for.
