Omnifocus Duplicate Project is a free software that allows users to replicate an Omnifocus project and replace placeholders with customized strings.
Although the script doesn't automatically move the new project to the inbox - support for this feature isn't included in the current build of OmniFocus - it's a great tool for streamlining your workflow.
To use the script, simply find the new project at the end of your projects list and move it to the folder you want it to "live" in. To install it, save it in ~/Library/Scripts/Applications/OmniFocus (if you need to create that folder). Then, you can use Customize Toolbar to add the script to the toolbar in OmniFocus.
All in all, if you're looking to save time and effort on recurring OmniFocus tasks, Populate Template Placeholders is a valuable addition to your toolkit.
