Feature Request: settings to hide/show map for each album/category

[m-mast]

Problem: if "Display map on category page" is set, loading top categories (albums with many subalbums and hundreds thousands photos) take too long time.

Possible solutions:

1. List of albums/categories, where the map is not shown
2. For each album (table "piwigo_categories") set "show/hide map" flag
3. Set "maximum photos to show on map" treshold; if album/categorie has more photos, the map is not shown
4. Any other approach?

It's an exciting plugin, but using it with a big photo collection does not allow me use "Display map on category page" option :-(
