A much requested feature has been the ability of view and edit more than one files in the editor simultaneously. This feature has been implemented in version control and will be made available in the next release.
Here are some screenshots:
Notice that there are two sets of tabs and you can drag&drop tabs from one set to the other.
Two files can be displayed and edited either vertically or horizontally.
Here we have two files displayed vertically and for each file we have a second editor view displayed.
