I’m not sure what the correct term is… but here goes 
When viewing the long list of pistons and you click on one and decide to cancel out, or hit back. Would it be possible to remember the approximate area of the list you were in so that we don’t have to scroll back down too much if the list is long?
Similar to the behavior of the ST android app when you view the details of a thing, then or Save or click back. You end up at the same area of the list before you selected the device.
