It doesn't take a lot of overhead to render the $button, even if it added
to every tiddler. This is especially true since it is added to the
EditTemplate, as there is usually only one tiddler (or perhaps a few
tiddlers) being edited at any given moment.
Even so, there is a way you can reduce the overhead even further by using
the $button actions="..." parameter, like this:
\define doCreate()
<$action-sendmessage $message="tm-new-tiddler" title="This is newly created
tiddler" tags={{!!tags}} text=<<now "Today is DDth, MMM YYYY">> />
\end
<$button actions=<<doCreate>>>Copy Current Tags and Create</$button>
When you use this syntax, the doCreate() macro is only processed when the
$button is actually pressed.
Note that this also causes the <<now>> macro used to generate the new
tiddler's text to only be invoked when the $button is pressed. This
produces a subtle but somewhat important difference in the resulting
tiddler's content.
For example, if you were to start editing a tiddler just before midnight,
but not press the button until after midnight, the date written into the
tiddler text will accurately record when the $button is pressed, not when
it was initially rendered.
