I just began using OmniPlan, and the ability to create recurring tasks and milestones was the first thing I wanted to do in order to plan out my project. For the moment, what might be the best workaround? Is there a fastest way to copy and paste tasks?

As for how the single vs. multiple levels choice, I would strongly prefer a way to do either one. Each choice indicates a different kind of repetition, both of which I would integrate into my project plans:

A repeating task on the same line indicates a task that is repeated without depending strongly on other tasks, such as taking out the trash, a task that might need to be done weekly regardless of the previous week's content.

A repeating task on multiple lines indicates a task that needs preparation for, such as a series regular presentations or meetings in which data from other tasks will be needed.

Repeating milestones could also be of use.
