As of version 1.6, the way to stage files in SourceTree has changed. Now, every time we select the checkbox next to an item, it is automatically staged.

Personally, I think the former approach was superior.

For instance, if we want to stage multiple files, in the previous version, I could simply select all the files, and then press the "stage selected" arrow. Now, I think we can achieve doing a multiple select, then right-click and press "Add" action. However, this is more confusing.

The other approach to do that would be to review each unstaged file, one by one, and then stage explicitly as we go. Before 1.6, I would just enable the checkbox for each file I want to stage, and sometime later press "stage selected". Now, every time I do that, it stages automatically, refreshes the window and if I have a big list of items, even the scroll position changes...
