The recent switch to "free" downvotes has a side-effect: As far as I can see, there is no longer a way to see questions one has recently downvoted.
This makes it impossible to find and revisit those questions one has downvoted to see whether they have improved, and if they have, remove the downvote, which is a pretty essential part of voting.
Can we have this feature "back" please?
A concrete suggestion by @Shadow Wizard that I second:
I would suggest clicking your own "votes cast" link should bring you to page showing the full list of posts you downvoted instead of linking to meta.stackoverflow.com/users?tab=voters
Also, Adam Davis has a full-fledged suggestion that I would totally support:
I'd suggest adding a tab that shows posts they've recently voted on (up or down) that have changed. This gives you what you need, without requiring you to click through each voted on post to see if it's changed. It will encourage users to revisit posts that they voted on, since it will be a first-class feature on their account page.
