Feedback for your website (not your app). When I want to add a new idea, I first search to see if that idea is already on the website.

When I search, the search results are not sorted by vote count. If they were, I would vote for the top voted app at the top rather than add another duplicate of the same idea. I see that there are many duplicate ideas each collecting a few votes here and there. For example, I think font color selection would be a great idea so I searched "change font color" and 822 results came up. The votes are 20 here, 5 there, 10 there, etc. It must be difficult for you guys to rate ideas properly. If there was 822 votes on that one item, I'm sure you would implement it with much priority.

It will be hard to match and merge all ideas, but I'm thinking you can do one major overhaul clean up and from there, force users to choose from that one main idea for voting, or adding their own if it really has not yet been suggested.
