Please add the ability to move/reorder tracks within a project. Possible UI implementations: * Drag & drop — There is a fair bit of space to the left of the expand/collapse button. This space could be made into a draggable item, which should get the ↕ mouse cursor on hover. * Dialog — For keyboard users, a dialog could be created in which the tracks are listed and can be moved up or down with a button. This dialog could be opened via an Action (bindable to a keyboard shortcut) and/or a menu item in the track right-click menu.
