Set a longer time period for changing your vote

I already tried to change my vote on several questions but I was not able to as more than ten minutes had past. Now, I wonder why there is only this short period set and why we have that restriction at all.

  • Answers can be edited which can lead to a need of reevaluation of your vote.
  • Tagging and accepted solutions might change over time which again can lead to an opinion change.

So at least the period to change your vote should be much longer, speaking about days or even month instead of a few minutes, but in my eyes there shouldn’t be any limitation at all.
