Thanks! Use this code instead:

javascript:(function() { function setTitle(voteAt, minutesAgo, originalTitle) { var voteIn = voteAt - minutesAgo; var unit = (voteIn === 1 ? 'minute' : 'minutes'); var newTitle = '<Votes in ' + voteIn + ' ' + unit + '> | ' + originalTitle; if (document.title !== newTitle) { document.title = newTitle; } }; function run(voteAt, originalTitle, voted) { if (!voteAt) { return; } voteAt = parseInt(voteAt); if (document.title.indexOf(originalTitle) === -1) { return; } var timeParts = document.getElementsByTagName('time')[0].innerHTML.split(' '); if (timeParts[1].indexOf('minute') !== -1) { var minutesAgo = parseInt(timeParts[0]); if (minutesAgo >= voteAt) { if (!voted) { document.querySelector('.PostFull__footer [title="Upvote"]').click(); voted = true; }; document.title = '<Upvoted!> | ' + originalTitle; } else { setTitle(voteAt, minutesAgo, originalTitle); } } else { setTitle(voteAt, 0, originalTitle); } setTimeout(function() { run(voteAt, originalTitle, voted); }, 1000); }; if (!document.querySelector('.PostFull__footer [title="Upvote"]')) { alert('Are you on steemit.com? In that case the bookmarklet may have stopped working. Please contact @lantto for an updated version.'); } else { run( 30, document.title, false ); } })();

The very last part run( 30, document.title, false ); decides. So just replace that with whatever you want.

I may actually make a separate bookmarklet which is simpler and just votes at the 30 mark as that's the most common use case (I believe). Great suggestion anyway!
