@treynterrio here is the code I've used where I get Enter Preset Name on both options (Add + Delete)
laf.registerFunction("drawPresetBrowserDialog", function(g, obj)
{
var a = obj.area;
var la = obj.labelArea;
var h = 40;
g.setColour(0xFF000000);
g.fillRect([a[0] - 50, a[1] - 25, a[2] + 100, a[3] + 50]);
g.setFont("arial", 13);
g.setColour(0xFF000000);
g.drawAlignedText("", [a[0], 50, a[2], 25], "centred");
if (obj.labelArea[2] != 0)
{
g.setColour(0xFFFFFFFF);
g.fillRoundedRectangle([la[0] - 0, la[1], la[2] + 0, la[3]], 0);
}
else
{
g.drawAlignedText(obj.text, [a[0], a[1] + 40, a[2], 20], "centred");
}
g.fillAll(noColour);
g.setColour(0xFF000000);
g.fillRoundedRectangle(obj.area, 0.0);
g.setColour(0xFF141414);
g.fillRoundedRectangle(obj.labelArea, 0.0);
g.setColour(0xFFFFFFFF);
g.setFont("Arial",16);
g.drawAlignedText("Enter Preset Name :", removeFromTop(obj.area, 40), "centred");
