Сustom plugin configuration UI

What exactly do you need that is not available with the current dynamic configuration options?  Just want to ensure you are choosing the best way to extend administration for your needs.

We need to make a password like a field that looks like a secret (stars or other symbols which make it hidden)

When defining your string property in your IConfigurablePlugin implementation, try adding the obscure = true to the property.

				var passwordProperty = new Property
				{
					Id = "password",
					LabelText = "Password Text Field",
					DataType = "String",
					OrderNumber = 1,
					DefaultValue = string.Empty
				};
				passwordProperty.Options["obscure"] = "true";

I've tried, but no success. In which version does it work?
