auto save task when back button is pressed

I think it's happen to all of us : we are trying to make a new task and someone call us on phone, or we receive important message => after, bad habits maybe, we close all the programs running in background...and we close tasker and we lost all our work !! :'(

The feature to auto save the task without clicking on the check mark on the top right side will be great

what do you think ?
