- the footer does not show the import progress on hover
- if Optimize is importing the loading indicator is showed in the footer for the respective engine
- if Optimize is not importing a green circle is indicating that the import is finished in the footer
- the footer section in the user guide documentation is adjusted accordingly
We don't compute the import progress in the back-end anymore, but instead return the import status. The import status is true if Optimize is currently importing and false otherwise. See here how the new endpoint looks like.
