Mobile editing process is quite cumbersome (for some reason listings are very buggy, notably references, whereas all is fine on desktop).
But a big productivity increase would be driven by a floating button for the modifications saving (instead of always scrolling to the very bottom, which regularly leads to unvolontary clicks on my browser modal asking if I should wait for the page to load or close it as it seems frozen according to it - you can imagine frustration when you just added several references and have to wait 5 seconds for each operation like opening the listing, finding your reference, selecting it, entering the number)
If it is possible! :-)
