Make OmniFocus as a checklist App.

• Maintain multiple checklist templates.
• Create a checklist in a single or multiple projects by selecting a pre-built template.
• Notes, Parallel and 'Complete with last action' properties and tags from the template are preserved while creating a checklist.

This plugin depends on the omnifocus-plugin-libdev library.

Clone the repo and link it in the Automation Configuration dialog in OmniFocus, or add it as a git submodule to the default plugin folder of OmniFocus. I recommend the latter for an easier synchronization with other devices.

cd ~/Library/Mobile Documents/iCloud~com~omnigroup~OmniFocus/Documents/Plug-Ins

git init

# Install the dependent library, ignore this if you have already installed it.
git submodule add https://github.com/xbot/omnifocus-plugin-libdev.git libdev

git submodule add https://github.com/xbot/omnifocus-plugin-checklist.git checklist

# For updating:
git submodule update --remote --recursive

• Create a folder for checklist templates.
• Create as many projects as you want under that folder, each project is considered as a checklist template.
• Set the folder as the template folder in the plugin's preferences dialog. (Click the menu item while holding the Ctrl key)
• Select an ordinary project and trigger the plugin action, then choose a template in the dropdown list and press the Create button.
