Gallery Add-on for Advanced HTML Editor

I use the Advanced HTML Editor with the online page editor add on and the Image Gallery add on and youtubizer and picas and file manager add on and nivo slider add on, all works great however a feature that i would love to see is integration of a layer popup within.

As an example I have a project that has a rally page, this gallery page has multiple sections, lets say you select the gallery, and within that page there is a gallery of food, another of people, another of functions and 10 others, I do not want the page to show 10 different nivo sliders or html 5 image galleries because it makes the page so slow, it would be great if instead I could have 10 links and once a link is clicked on it opens that particular gallery of images in either a pop up window, or a lightbox or even an accordion drop down or something.

For an example of what I have managed to do so far take a look at http://www.thomasmore.co.za/Thomas-More-College-Gallery-2011

it works but it is slow, and the largest issue is that I have to do it for my client as it requires me to go into the html code of the editor to add the next accordion menu and once added I can not select the nivo slider easily because I can not see it to select it. There has to be a better way to do this in a manner that is still easy for my client with little coding knowledge to manage, maybe with the hyperlink / popup layer solution.

Please let me know what your thoughts are on this. 

Folder View for Documents

File View is fantastic.  I certainly have uses for it, but currently I have a need for exactly this extension but for documents i.e. .docx, pdf, xls etc
