Microsoft has just published that they will start to roll out a lot of new functionalities to your SharePoint lists, so pay attention to your environment when this updates will arrive.
Column totals
Now you can summarize also for instance costs in your SharePoint Lists, giving us a lot of possibilities.
Add Columns in between columns
This will help all people out there that have already built a list with columns but afterwards realize that some columns are missing and you want to put them in between the already existing columns
So Chris McNulty and the Microsoft Team, thank you for once again shipping great functionalities to us, so we can create better solutions on top of this.
