To create a new folder in the SubTool subpalette, select a subtool that you want to put in the folder and then choose the New Folder button; the Please Enter Folder Title window will be displayed. Next, enter the name of the folder in this window. You will notice that the new older with that name is created in the Subtool subpalette and the selected subtool will move to the folder. To add more subtools in this folder, select the subtool and drag it to the folder; the selected subtool will now be a part of that folder. Note that you cannot create a folder within the folder. Also, if you delete the last subtool from the folder, the folder will be automatically deleted.
