#####################
## Version 05/2020 ##
#####################
## Features of this version:
## * use maketimer, only update visible pages
## * use props.nas, store in local variables where sensible
## * store instrument directory in variable
## * clarity through indentation
## * use functions for common functionality
## * clean up listeners
