Often I visit CV via my mobile phone because during the day I am out for work, etc. With the smaller screen and the imperfections of a touch device I have experienced a few instances where I approved an edit or post without having the intention of doing so (rejections aren't the problem because there I have a follow-up screen before the review is final). As it has just happened again I have become sufficiently fed up with my phone in order to write this question.
Would it be possible to have a short period after a review in which it is still possible to change it? I'm talking about something like 10 seconds or so, such that this kind of mistake can be fixed immediately if one realizes that this has happened. After all we do allow for retraction of up/down votes on the site for a certain period as well.
