I think that the Software Database needs to be extended. It's a great function and needs more improvements. The Click'n Run function is great, so I recommend you to let people use it in another pages. You can put a script creator that generates HTML script with a button saying " Have Linux Mint ? Make an Easy Download ". Then they may be redirected to the download page. For developers I think this would be great.
To finish I just recommend you to make a better design to the page, like you did to Ubuntu.
