You can now move tabs (and sub tabs) to base tabs. In fact, our new move tab interface lets you easily move any tab anywhere in the binder.
Also in this latest release is the ability to set a default tab color for both sub tabs and base tabs from the Binder Settings menu.

Thank you! I especially appreciate greater ease in moving tabs — when I use “LiveBinderit”, I love the convenience, but I disliked the tedium of them clicking “move tab left” “move tab left” “move tab left” — to get the tab in the appropriate location in the binder.
