Hi Danielo,
there is no way to prevent your macro is refreshed on every keystroke
when it appears in a tiddler's preview window. Doesn't matter if you use
macro or widget. Your only chance to control the behaviour if you put it
somewhere else where the parent does not completely refresh all the
time. Then you can control the refreshes via the refresh function of
your widget by simply ignoring all the tiddlers in changedTiddlers that
are drafts (have a field "draft.of").
