The current commit UI is pretty painful. To include, or exclude a file you have to select it from a drop down list. An
interface more like TortoiseSVN would really be a lot easier to work with. In that interface you just tick a checkbox if
you want it in the commit or not. If the file is new then it automatically gets added for the commit. It also has a
"mark/unmark all" box at the bottom which does exactly what it says. There is just no way to quickly go through the list
for commits while using a drop down list.
