Undocumented my-ideas filter

While researching an enhancement to our Idea Exchange platform, I accidentally stumbled upon a "my-ideas" page that appears to be a filter to the ideas database that shows only those ideas submitted by the currently logged on user. Lithium support has not been able provide any documentation on it, and suggested that I post here to see if anybody has knowledge of it or used it.

To use it, I merely changed the last part of one of the Idea Exchange pages to 'my-ideas' like so:

https://community.acer.com/t5/ideas/v2/ideaexchangepage/blog-id/Acer/tab/my-ideas

So, does anybody have any knowledge of this "my-ideas" filter, and/or what other filters are there that exist?

Why hasn't Lithium make this filter known?

It's not mentioned in the Implementing Ideas document, or any other doc I've seen, and I find no references to it anywhere in the Lithium community.

This appears to be exactly what we want but I hesitate to implement it without a little more information or assurances that it will continue to be around and function as expected.

Any help, comments, links, suggestions or information is welcome.

Thanks.
