I like Blogger for its simplicity, but also wish for more features at Blogger. I stumbled upon a help page where you can inform the folks at Blogger on what features you would like added – a wish list of sorts.
As the page puts it
If we don’t offer it yet, let us know about it. We’re constantly working to improve Blogger, and we appreciate any input. While we don’t reply to individual suggestions, we do review them all and will keep them in mind for future development.
The radio button only allow submission of one suggestion at a time. So if you want to vote for multiple items, simply go back in the browser and vote again.
