New feature in upcoming dabblet v1.1: Complete control over number and layout of tabs. The “template” accepts a syntax similar to what the
grid-template property does, assuming r is for the result pane, c is for the CSS pane and h is for the HTML pane.
The “see through code” option will make the result full-size and the code will have a transparent background through which the result can be seen. Similar to current “Behind code” view but more customizable.
