Sometimes I collect the daily writs so that they are 'ready' then when I have more time, I log in again to complete them. The advantage here is that if it's past the daily writ reset time, I have a full set of dailies to do and then I can collect the fresh dailies and complete them also.
The problem is that when I log in again, the very handy toolbar won't reappear until I do one of the writs.
