i guess you could achive this via css.

Creating multiple containers with Header names.

When clicking the header name u switch the showing containers.

smth like this:

Then maybe via SOTI Surf?

But otherwise id say you have no chance.

SOTI's default template will only get you so far.  Just like with any default template webpage you're going to have to code your own functions if you want some functionality that doesn't exist in the code already. If you wanted to switch how the page looks with certain buttons, you need to code all of that in the template itself. 

Same thing with folders since i dont think that's part of the default code template.

The purpose of the lockdown is not to allow for multiple pages or organizational tools, its just a single page designed to quickly and easily present a list of functions.  Its very simple in its default functionality, but with the right knowledge anything is possible.

You would need to use CSS to accomplish this, I would do it using multiple divs and a bit of Javascript to switch between them. We use a variation of this to have multiple pages that can be scrolled through (as we need up to 30 icons on our devices).

I did a quick mock up of this for you @ https://pastebin.com/ewZjubWN

I added the images just to show what it would look like, but in reality these would be taken from the MCEXEIcon (except the folder image).
