Remember opened "sub-folders"

[fredefox]

In the HTML output I think it would be super useful if folding a parent folder with multiple open children would remember what children are opened. Would this be reasonably easy to add? Are you open for PRs? I might be interested in working on it. Would be great if you could point me in the right direction to get started.

Thanks for the tool!

I see that the children are added to the DOM only when a folder is expanded and removed again when it is closed. So perhaps this is not so straight forward.

Is there a specific reason that not everything is added to the dom on the initial page load? I'm guessing there might be a great deal of HTML that would need to be generated for large profiler outputs...

Yes, adding all of the children is not really possible for large enough profiler outputs, the browser will just end up freezing.

I don't see anything wrong with keeping the children around when closing the parent though.

Cool. So we would need to modify the close-operation to simply just hide the html element and then we need to modify the open operation to check if the subfolder has already been generated.

Sounds easy enough.
