Two questions about Records

Question

1. Can I put a back button on an invidiual record after clicking a recordLink to go back to the Record Grid with all the records? 
 
 I have a grid Record Type that lets users see and filter for specific records, when they click on the record link to go to that specific record, I want a back button on the interface displaying the data to go back to the Record 
 
 2. When I sort columns in a Record grid, can I make it so that it ignores null values? like if the values in the column are 1,2,3,4,5,null,null,null,null,null,null 
 I want to see it sorted these ways: 
 5,4,3,2,1,null,null,null,null,null,null 
 1,2,3,4,5,null,null,null,null,null,null 
 
 Not 
 null,null,null,null,null,null,5,4,3,2,1

For your second issue, you should be able to repurpose this code to achieve your sort. 
 load(
 local!list:{1,null,2,null,3,null,4},
 local!ascend:true,
 local!sortedList:if(local!ascend,sort(local!list),reverse(sort(local!list))),
 local!listNoNulls:difference(local!sortedList,tointeger(null)),
 local!listOfNulls:local!sortedList[wherecontains(tointeger(null),local!sortedList)],
 {local!listNoNulls,local!listOfNulls}
) 
 Just make sure to tie the local!ascend definition to your actual descend vs ascend logic. As for the first issue, short of instructing your users to right-click/open link in new tab, is there anyway you could put the record link within an a!safeLink()? This will at least open the record in a new window and keep the record list open

For the first issue, the Records interface already has built-in functionality to accomplish this via the breadcrumb links at the top -- just above the current record entry's title will be linked text saying "Records / [Your Record Type Name]", and by clicking on "[Your Record Type Name]" the user will be returned to the record listing. They can also press the browser's back button. There really isn't any need for yet another back button for this - and AFAIK it's not possible anyway.
