Importing Data: Faster and Easier Mapping
We've further refined the mapper to make it quicker and more intuitive. Here's the new design:
In addition to the design refresh, we have streamlined the data import process to only three steps. There's now a link to create a mapping template on step two, in addition to the link on the final step. We also significantly improved the performance of the mapper, which you will notice if you import files with many columns. 
We now validate file formats prior to upload, so that you don't have to wait for the upload to complete to learn that you accidentally chose the wrong file. To help prevent this type of problem, we added some succinct instructions on file formats and formatting.
