Often we find ourself using the same connector over and over again. For example, we set a trigger from a SharePoint list/library on item created, modified, deleted, etc and then we send it for approval. Upon approval or rejection we need to update the same item or create another item but we are still needing to use the same list or library connector. So, it would be very ideal if we can save the list/library connector alike to a variable and re-use it throughout the Flow. It is particularly usefull when we need to make a copy of the Flow and target it a different list or library so we don't have to go around around and change all the list pointer. Re-pointing connector is a very tidious task and it is prone to mistake.
