In A one can see that Chopin initially wrote  to mark the time signature on both staves. Moreover, the eventually left 6/8 reveal (also on both staves) minor crossings-out, which seem to be digits preceding the digits 6, although it is difficult to guess what their meaning could be. Anyways, it is an example of Chopin's hesitation, since the time signature in FCI, which was written earlier, is 6/8, like the final version.

Initially, the slur of A in bar 2 ended on the last note in this bar (same as in bar 1). Chopin, while adding the slur in bar 3, ensured that it is added to the previous one, which can be considered as a template for all similar situations.

In A there are visible traces of deleting the original version of the 1st quaver in the L.H. It seems that its notation did not go beyond the staff, it could have been, e.g., the F-c fifth.
