This should be fairly easy to implement: for each type of individual feature we have in WME just have a flag that we can turn on and off to disable the display on the map.

I have a fairly high end system, high end graphics card and 2K (full screen) monitor. When encountering areas of the map that have large amounts of polygons (like for water objects) really can degrade the responsiveness of WME. Plus: being able to dynamically remove these objects reduces map clutter for the editor.

This looks like a duplicate of "Forests in separate layer"

Franky, I'd rather the dessert, Tony ;)

I'm hoping you meant "Desert" and not "Dessert" :D

Hi!
Agree with @bobbyqat; in Bahrain, almost 50-60% of the map is covered by layer "Islands" and making it very hard to edit the map due to multiple layers

Yes please! There are times when you only want to turn off certain place types. Either you want to turn off large area places because they are in the way, or you want to turn off places (because there are lots) but leave large areas so that the map draws quicker.

Especially when the coastline is wrong and is corrected by "island", a city along the sea can be fully covered by a place "island" which isn't easy to manage

Perhaps these could be merged with the hidden water layer and editing of those objects could be enabled for end users. We have many false 'island' place types in coastal areas to correct inaccuracies in the water layer.
