NOTE - Neither issue is critical because there are workarounds, but I wanted to make sure you were aware of the issues.

Mouse triggers appear to be connected

For "layer actions",  the "Mouse Enter" and "Mouse Leave" appear to be connected.   If a javascript function is linked to the "Mouse Enter" trigger, and a different function to the "Mouse Leave" trigger, whichever function was defined last will be called for both triggers.

for example, 

    "#button" has 
        button_enter linked to "mouse enter", and then
        button_leave linked to "mouse leave", then
        button_leave gets called for both.

    "#button" has 
        button_leave linked to "mouse leave", and then
        button_enter linked to "mouse enter", then
        button_enter gets called for both.

    I get around this by linking a single function to both events, 
        and testing for $('#button:hover').length != 0

Linking to a layer messes up the Mouse triggers

If I set a URL link for a layer that has a function linked to the mouse triggers, the function doesn't get triggered.

The workaround is easy - just don't link any URLs to layers with mouse triggers, and implement the links via javascript events.

    $('#button').on('click', function(event) {

               // do stuff

    });

Thank you!
