As you can see I ended up with two of the same name, since I thought the first save didn’t work (it’s also quite surprising they don’t have to be unique names, I guess I would have thought it would prompt me to overwrite the first save, but that’s another story).
I think the sidebar needs be refreshed whenever a new dash or report is saved.
