Maps / Place names

Would it be possible to improve place name rendering?

Attached is a screen shot of France taken from the LoMaps city theme, compared to Stamen's toner (my device has a grayscale display).

Notice that the LoMap shows Argenteuil instead of Paris most likely because Argenteuil is rendered before Paris.

I've just finished the first draft of a theme that I use on my e-ink phone. The xml and svg files are on gitHub https://github.com/gauvins2/mapThemes

Attached is a comparison of the stock Hike/Bike theme (left) and the hcLayers (right).

My understanding is that the zoom level at which a map feature is visible is determined by the map data and not by the theme that is applied to it. If I am wrong, please correct me. Otherwise, is it possible to edit the *.map or *.db in order to change the design setting?

This wiki entry suggests that small roads become visible at a zoom level of 15 or more https://wiki.openstreetmap.org/wiki/Zoom_levels. I'd like to be able to see them at a smaller scale. Idem for some POIs such as campsites.

I use an e-ink phone (Hisense A5) and would like a high contrast theme similar to Toner (https://openmaptiles.github.io/maptiler-toner-gl-style). The OSM theme definition can be found on GitHub https://github.com/stamen/toner-carto.

I know nothing about theme development. Could someone point me to useful resources? Ideally a walk-thru to convert an OSM theme to Locus. (or even better, a Locus port of the OSM theme :) )
