Astr.io has this and i think it should be implemented into senpa, an alternative to the active cell border, there should be a new option which puts an arrow above all cells in the active tab or the biggest 2 or 3 cells in the tab, i also think there should be a seprate option which allows you to see arrows above your teammates tabs, i personally like to play with names and skins off but i can’t do so if i have a teammate, to make this less confusing the arrow above your teammates cell should be a different color then the one above your own.
