Save Current IFS to List
Each item allows you to save the current IFS from the IFS window to the list of fractals. The second option will first request a name for the IFS.
Add Current IFS to List As...
Delete from List...
Choose this to bring up the list of the IFS's that are currently available. You can then delete one or more of them from the list. This cannot be undone so be sure to check only the names you really want to delete! The one exception is if you check to delete the current IFS shown in the IFS Window. You will be asked to confirm that deletion.
This will clear every IFS from the list. This cannot be undone so use with caution.
Click on the name of an IFS to load the parameters into the IFS Window.
