Not sure I selected the right category.
I think it would be useful to also add the option to downvote an idea.
Ideas/feature with e.g. 100 votes can get implemented while maybe 1000 people don't like the idea or feature to be added.
Having a downvote option as well may indicate this and prevent unwanted features to be implemented.

This highlights the importance of options. It's OK to implement an idea that not everyone wants, needs or even likes, as long as the user has the chance to hide it or turn it off if its not useful to them.
