When using the "Search" in SourceTree, I now have to choose between file changes, branches, commit messages, SHA and users. 
I'd rather have SourceTree search all categories, or multiple categories. When I search something, I just want to enter what I search for, and not have to select some category to be able to find it. My default categories would be SHA, commit messages and files.

Also: when searching in file changes, it is not clear to me which file the change occurred in. Some highlighting of the files that contain the changes would be nice.
