This topic is perhaps the best example of problems with Feature Requests. The current topic was created almost two years ago but has only been given 2 votes.

It has attracted a lot more than 2 votes.
The issue has been tweaked from time to time, but it's never been resolved.

Some are marked as 'implemented', but the issues are still there:
