Fastest way i found to make small changes on your site is to use FTP program like FileZilla. Then you just go to file you want to edit and click view/edit. File is downloaded locally and opened in your default (or the one you set in FileZilla) editor. Then you just change what is needed and after all is done just confim on FileZilla that you want to upload changes.

so put it in function
