Add numbers to tabs for keyboard shortcuts

It would be helpful to have a small number on each vertical or horizontal tab (whether collapsed or expanded) so that users can easily know what shortcut number to type to access that tab. On MacOS, for example, to reach the third tab, users would type ⌘3, for the fourth tab ⌘4 and so on. This shortcut saves time and a small number on the tab itself would make it more efficient so users don’t have to count the tabs before they type the number. Thanks for your consideration.
