persistence

Hi Warren,

thanks for providing this.

I was actually thinking a little different.

As one is working on a mindmap, there possible more versions. So one need to select which one to work on.

On my screenshot you can see how I envisaged this. These buttons are not working, but an addition to the helpers.swift file.

BTW: sibling is not needed because with child you can create the same by selecting the parent.

kind regards,

Tim
