The roadmap styling needs to be improved - it's not dense enough and somewhat confusing. It needs to be a lot more compact and only expand descriptions on click.
We need to perform exponential backoff on status checks for sites which are persistently down, so that we don't waste lots of resources checking them every second.
Allow sending alerts (SMS and email) when a new event has been open for x seconds/minutes. Only send one alert per user per event, and only send to teams, not to customers.
Import issues from bitbucket and github. Starting with bitbucket zip exports, possibly also support signin via these services to allow import via the account.
Import issues from asana might be more useful.
I think we have import from bitbucket now, but decided I don't want it!
Add a see also section on each issue, which lets you add other issues which are related. These might be dependencies, duplicates or just tangentially related ones - there are often varied reasons for referring to other issues so good just to have a loose link between them.
Show a list of possibly related issues on issue create, when you start typing, above the Add issue button, so that the user can see if a similar issue already exists.
A way of inviting users to participate before a project is launched, and keeping them on a list(s) so that you can let them know when your project launches.This could also be used as a way to promote growth later via user referral schemes, with a little modification.
A timeline of work completed and work to be done later chronologically - showing the past as well as the future, and allowing filtering on user, tags and other criteria.
Issues should be linked to the customer list for a project, so that you can easily see which customers are interested in a given issue, and which issues are open for a given customer.
Allow hosting a project website at project page. You can host your entire website at project page if you wish, or just certain components of it, like your community, your public roadmap, or your status page.
Community is really important to finding the customers you need, and to nurturing your relationship with customers. From product ideas to bug reports, a public community helps you build trust with your users and communicate clearly with them.
