So right now the mobile client just opens google maps in a web browser when running the "showMapForAddress" function. It sure would be nice if it opened the native mapping application. I already use this, but it would be nice if it was included in the stock mobile client.

showMapForAddress: function(address) {
            if (navigator.userAgent.match(/ (android) /))
                window.location.href = String.format("geo:0,0?q={0}", address);
            else if (navigator.userAgent.match(/ (iphone|ipod|ipad) /))
                window.location.href = String.format("maps:q={0}", address);
            else   // web browser
                window.location.href = String.format("http://maps.google.com/maps?q={0}", address);        
        }

 This just does a browser check and returns a hyperlink accordingly. If you're on Android it will open your default mapping application (normally Google Maps, but you can change it to be another App). If you're on iOS it opens the google maps application. And if you're on neither it just redirects you to google maps as normal.

I can only add new Contacts to an Opportunity. I need to be able to add existing Contacts as well.

Ideally, i would also like to be able to select a Contact record on Opportunity entry.

Scenario 1: Create a new Opportunity from a Contact record. The contact record you were in is added to the Opportunity but you can only add additional new Contacts to the Opportunity

Scenario 2: Create a new Opportunity from an Account record. I cannot add a Contact at Oppo entry. Once the Opportunity has been created, i can only add new Contacts to the Opportunity- not link to an existing opportunity.

Scenario 3: An existing Opportunity. I want to add an additional Contact (having just found out the Decision Maker, 3rd Party Consultant etc). I can create them as a new record but I cannot add them if they already exist in my SLX database.
