As a Series S player, it is unfortunate but understandable to hear that some layers will be disabled on Frankfurt-Fulda, but it is a bit bizzare that layers cannot be re-enabled through the layer manager. Imo it would have been nicer if we could enable default disabled layers (e.g. AI S-Bahn layers, as most can be seen for only a few seconds emerging from tunnel, but use a lot of memory.) and enable others. And would also give the layer manager a new purpose.
I don't quite understand that either. Why not just give the players a fixed amount of Layers and then let them switch between layers.
