having the shortcut like CTRL + A will help a lot, adding the options to change the color of tabs is also a great addition.
Excel already supports Ctrl+A, and you can change the color of sheet tabs by right clicking on them and choosing “Tab Color.”
Hope that helps,
Ctrl+A to select all text within a cell.
