2 questions

Hello again Victor, I have 2 questions. First, Can u activate the searchbox in my worksheets section? There used to be a box to find among my worksheets. Second, Isn't it a way to update worksheets which are already done? I mean that I can update it by uploading a new document since sometimes I'd like to make several changes and I wouldn't like to do the worskheet from the very beginning... THANKS !!
