I upgraded to SourceTree 1.9.5.0 last day and check boxes on left side of files in filestatus lists are gone since then.
Here is a picture of what I see currently in filestatus view:

There used to be a check box on the left side of each file which allowed me to switch single files between Staged and Unstaged lists very fast.
Is there anyway to get the check boxes back like previous versions?
