Indeed you are changing the tag, but the property will change along
with it (check it!).  The idea is that the property is *tracked* by
a tag, to make the current value constantly visible.  I use the tag
interface just because it exists and is simple to use.

Which will cause a change in the property as well, I believe.  I know
it is confusing - but once you've got your head around this, it will be
very useful.

That could be done, but you can also set the startup option.
But yes, it is one more think to remember...
