Restrict access rights within a project

Feature request … SUB project (like subtasks but for projects)

The reason/idea behind this is for use with guests as it would be useful to give access to people based on a specific part of a project and not the entire project. Right now, there is now there is no way to limit access, so you either have to share the entire project or create a separate project so give guest access.

This is being considered for V2 of SmartTask
