Text layer as a check

t = clamp(t,1,index-1);
thisComp.layer(t+1).name;
Layer slider with responsive positioning
Parameters:
Layer can be aligned in x-axis with adjustable even space in-between 
For that to happen, the anchor points of the layers must be centered
This prevents inconsistent opacity for the layers on both sides
If a layer scale changes, the spacing should change accordingly
Create a control that just change the active "tile";
Tiling formula
(target.width/2−space)−(active.width/2)(target.width/2-space)-(active.width/2)(target.width/2−space)−(active.width/2)
