+for all projects in your group. Select the project you'd like to add an issue for 
+from the dropdown button at the top-right of the page.

+![Select project to create issue]()
+
+We'll keep track of the project you selected most recently, and use it as the default
+for your next visit. That should save you a lot of time and clicks, if you mostly 
+create issues for the same project.
