The lazy loading of Ant build files is annoying. My build target shortcut keys don't work until I open the Ant toolwindow after loading the project. I've filed a JIRA issue about this already: http://www.jetbrains.net/jira/browse/IDEA-12906
Why can't the Ant build files be loaded during project load?
