The latest Android update makes the user interface more like the iOS interface. That is a big improvement on several aspects.
When I select a song from the list I noticed that when I transpose a song for playing, the original key is still outlined so it is easy to revert the song to its original key.
However, this is not possible for other settings like tempo changes.
In general, I would like to be able to make a temporary change and then revert later.
For the song editor, I still miss UNDO.
