Attached two screenshots.
Now it would be nice to add mor than one overlay.
the overlay selection dialog is fine, just be able to add/remove more layers and ability to change the order.
For hillshade it would be nice to add hillshade layer more than once to exaggerate the shade.
Don't know if you like to add this layers in the online maps section of locus? If you do, should I try to get the permissions or would you do it? By the way, cmarqu, the maker of HikeBike map (and the hill shade tiles) is already on Satisfaction...
Edit: changed the providers to match the ones created in
