How to split a pane from the ⋯ menu

Published by BetterStage · Instructions for our macOS app; detailed feature reference is linked below.

Steps

  1. 1

    Turn TabStack on, then click ⋯ on the pane’s tab bar.

  2. 2

    Choose Split Side by Side or Split Top/Bottom.

  3. 3

    That creates an empty sibling pane. It does not move the current tab — tab-menu split is a different action.
