In the Task Manager you can setup and save Task Templates (Checklists) that you can load into future projects.
Unfortunately, if you want to edit an existing Task Template you have to load in the Task Template to an existing project, edit the tasks and then re-save it as a completely new template.
This process is not efficient. Users should be able to easily edit an existing Task Template from your Workspace Settings (just like you can edit Estimate Templates).
Solution
Create a Workspace Task Templates area where users can see and manage all of their existing Task Template checklists that they have saved in their account. If they want to edit and existing Template, they can click "Edit Template" and edit the existing tasks and information.
