stage/unstage files showing like a tree

Is there a plan to show stage/unstage files in a tree so that I can expand/collapse all files in a folder. 

In our projects, there are some of files that we don't want to see them even these are display in the unstage list and we cannot set them in .gitingore files.

A good way is to collapse them. Currently, I have to select only a few files in lots of items and it's a trouble for me.

Thanks,
