If you try to create a filter from a stored selection, but have no stored selection, you don't get any submenu. This can be confusing: doesn't the sub menu work?

I suggest that we add a disabled menu item to the sub menu as long as there are no stored selections. This menu item can be called "No selection available".

While we are discussing this feature, I think the menu item in the context menu can be a little misleading too. "Add Filter from Selection". It would be reasonable to make a selection in the table below and expect that selection to be used for the filter creation. We should try to name the menu item better, to explain that it is from the list of stored selections that you can create a filter.
