I'm using the latest:

For each sheet.sch file I currently generate a sheet.pro. I
copied BOARD.pro to top.pro, opened project top.pro inorder
to have the proper library list. I see kicad generates an empty
top.brd but not a top.sch, so to produce a top.sch I opened BOARD.sch,
new schematic, added a sheet and tried to rename the file but it
didn't crash or take. I had to save and exit. When I got back in 
top.sch, then I could rename the sheet file name, get the prompt 
and change the file name.
Since kicad no longer shows the eeschema, cvpcb, pcbnew symbols,
it would be nice to generate a empty project_name.sch if it doesn't
exist.

Nice feature. I hand edited a top.sch, was able to navigate
into the sheets, and generated a reasonable looking top level 
netlist.

thanks for all the work producing this awesum tool,
