====== About the script ======
  * Purpose : Change the label of an item to make a page indicator

====== How to use the script ======

Important: due to the custom characters I use, the maximum number of pages is 10. However you can change the character as you wish.

Instructions:  
  * Copy/paste this script as a new one
  * Set it to run in the 'position change' event of the desktop
  * place an item (recommend: shortcut to 'do nothing' and pinned) and label it 'indicator'.
  * [Recommended] Check the snap to pages and uncheck 'fit desktop to items' in scrolling options.
It automatically adapts to the desktop, for this reason the home page may not be the number 1.

====== Script code ======
<sxh javascript>
//The special characters
var fill = "➊❷❸❹❺❻❼❽❾❿";
var empty = "①②③④⑤⑥⑦⑧⑨⑩";

//Vars
var cont = LL.getEvent().getContainer();
var width=cont.getWidth();

var left = Math.round(cont.getBoundingBox().getLeft()/width);
var right = Math.round(cont.getBoundingBox().getRight()/width)-1; -
var page = Math.round(cont.getPositionX()/width);

//With zoom --> no page selected
if(cont.getPositionScale()!=1) page=NaN;

var ind = "";
var flag=false;

//if more pages, just show "..."
if(right-left+1>empty.length){
	right=left+empty.length-1;
	flag=true;
}

//indicator
for(var i=0;i<=right-left;++i)ind+=(left+i==page?fill[i]:empty[i]);

if(flag)ind+="...";

//apply
try{ 
	item=cont.getItemByLabel("indicator").setLabel(ind);
}catch(e){
	alert("Item not found. You need to label an item 'indicator'");
}
</sxh>
