A new parameter to set the order in which the panels are filled has been added.
I think it is not critical to include it in the master branch. Whenever you have time, @aho, could you take a look?
I did a test example: https://earth.bsc.es/gitlab/nperez/Flor/-/blob/master/s2dv/PlotLayout_test.R
Please, Jaume, let us know if you have any problems.
Cheers,
