As you start developing a large number of modules, it becomes increasingly long-winded to check on the published status of the modules. A simple way to make this easier would be to:
1. add a column that shows the current latest build number AND the published build number for each module
2. maybe also add columns to show the latest build date and latest published date in addition to the current creation date
Maybe also worth showing all the above information on each module page so, at least, you don't have to click on the build "button" to see what the latest build and published versions are.
