How can I remove currency value displayed in Opportunity kanban view?
 

I need to pass some URL/query parameters between Visualforce pages which are embedded in the lightning app.

Let's assume URL is -
https://cs1.lightning.force.com/one/one.app#/sObject/Opportunity/new?Unit__c=a0Zp0000002mja8ETA&isdtp=p1

So how can I access Unit__c in the controller?

The following code segment is not working with Lightning.
ApexPages.currentPage().getParameters().get('Unit__c')
