It seemed to work OK at first, but...... after I used it to edit a spreadsheet, and saved my changes every edit, it didn't save them. Also, I created some piles to save PDF documents in , and it can't seem to find or navigate to those files and folders. Chrome has a default editor that seems to do much better and I'm switching to using that one
