It would help to be able to enhance visibility of country borders, e.g., around Ukraine.

A toggle feature for selected layers would be convenient, e.g., 'wind' and 'wind gusts.' In other words, click on the layer menu item and it toggles to its next state. You could even color those menu items to indicate they have a toggle option. This would save us having to click on 'More layers...' to go from e.g., 'wind' and 'wind gusts.' Of course, the toggle could exceed binary options, but that could prove to be a nuisance if the additional layers are only rarely used. Good heavens, you could have a Settings switch that would limit toggling to to binary selections of the most common options, or all options, e.g., with 'clouds.'
