When checking code into via 'Source Control' it displays the 'Working Tree'.
The problem is that the UI does not make it clear which version is the 'edit' version and which is the original 'unedit' version.
I will often come back to a project that has some outstanding commits and not remember specially what the work was. (I often get dragged away on other projects with incomplete work).
It will make life much easier if the UI gave a clear indication as to which window was showing the edited vs original version of the code.
