I would like to see an easier way to change the label on a group of sources. It would be nice to select several sources all at once and make one change to all selected versus going to each source one by one to make the change.
agreed. we hope to make it easier in the future, but until then there is a way you can select multiple sources from the sources sidebar, by holding down 'ctrl' as you select multiple sources. give that a try and let me know if that solves your problem temporarily.
