To keep track of all the suggestions, we use Feature Requests pages on our user-editable Wiki:
1) Feature Requests
2) Pending Feature Requests
Here the requests are sorted into categories, and each request has a tag where votes can be added. Therefore, Feature Requests made on this Forum will expire after the topic has been inactive for a month, and then be summarised and moved to the Wiki, or their votes added.
If you are experienced in using Wikis, you are most welcome to ask for a Wiki account, then you can add your new feature, vote or comment directly to the Feature Requests page without using the Forum.
