I like to call these "tk-vars". I use them all the time especially for CheckBox an StatusLine code.
It's interesting how they are "full-duplex" and dynamically update the widgets data with a minimum of coding.

It seems that the Save button is still functional after setting ..trace_add (subject_var_trace_add and cat_var_trace_add). Do we need to disable the Save button after set the trace functions?
