Enable compatibility with SimpleSpec styling schema for GEOJSON/KML imported layers ?

[cmoffroad]

I just started using umap, and it's pretty awesome.

Right now, it seems you can only tweak the style of an imported umap layer manually.

Looks like umap layers doesn't come pre-loaded with the SimpleSpec GEOJSON schema, which would be a cool feature for quicker visualization.

With SimpleSpec, you can specify at the feature level things like fill and stroke color, opacity, and width. It works with different software like Mapbox, and Google Earth even supports its port to KML/KMZ.

For example, using OSM data, I create various GEOJSON/KML datasets with gradients or surfaces and view them in Google Earth. It would be fantastic if I could easily share some of this data online through umap!
