You can continue working offline on all the content in your local archive. Once you are back online, you can then push your work to the company’s archive (signer archive) for safekeeping. You can find the content of your local and company archive in the editor by selecting “open”-> “All types”.
In addition, the section “Draft types” contains a subset of the local archive. It holds all the types you are the writer of, and that you have not yet pushed to the company archive. It means that anything in the “Draft types”-section only exists on your local PC.
