create new file at sidebar

Thanks for new update and now , I can browse file easily. However, I can't create file from sidebar. Mostly , I did like right click on folder and click new file or new folder. But this feature is not include in Textastic Mac app. If you put this feature on next update , it will be easier to create new file or folder at the current project. Now, I need to create new file and chose the save directory when writing the code in same project.
