Hi,
For those who say that it is default functionality: please read carefully, because I cannot express clearly in english :)
So, my question is: How to display different layout configurations depending on the screen size - is it possible with Omega to clone the functionality of AdaptiveTheme? What I mean is for example when user with iPad visits the site - some of the side regions are in the bottom of section, when user visits the site in HD resolution - they are in the side of section.
It is quite impossible to do that with media queries, but it is more or less possible with Context and Delta. The problem is, that I have found only single module https://drupal.org/project/context_resolution which is made for that, also it may be not suitable for phones/tablets with rotating screens and it is very fresh and untested.
What are your solutions? How to do this in "Omega way"
Thank you.

Read the Omega documentation
Read the Omega documentation PlayfulWolf. It's all there. And it's all there. A quick way to test what Omega does by default would be to throw some content in and see what happens. Generally speaking all the content regions will stack one under another from top to bottom. I presume you have a design in mind while trying to figure this out?
Q.
I have read ALL the Omega
I have read ALL the Omega documentation and many of the screen-casts. What do I want is intermediary layout: it is NOT all the regions in one column but rather in different column configuration. If you used any of AdativeTheme sub-themes you know what I mean
Example
"HD" resolutions (>1200px width)
|----content----| |-sidebar1-| |-sidebar2-|
"Tablet" resolutions (~800-1000px width)
|----content----| |-sidebar1-|
|----------sidebar2------------|
Mobile resolutions (<800px width)
|----content----|
|----sidebar1---|
|----sidebar2---|
Omega can do "HD" and "Mobile", but not "Tablet". Again, AT themes have this in the settings page.
Correct me if I am wrong.

@ PlayfulWolf Omega has by
@ PlayfulWolf Omega has by default the following layouts:
Mobile
Narrow
Normal
Wide
You can alter the mediaquery on narrow such that it works up to 1000.
I was about to say you can't
I was about to say you can't do that with standard omega/context as context doesn't support resolution detection but I just spotted this new module:
http://drupal.org/project/context_resolution
I haven't tested that yet but will. Full cudos to and support for theDuke there. That module would be a God-send for everyone creating responsive Omega layouts. I'll test it later too.
Good luck Wolf.
Q.
I am sure there is a better
I am sure there is a better answer as I am only new to Drupal and Omega but the couple of times I have had to do this I used PHP to clone everything from my sidebar2 into an empty region (that was full width and forced to render), and then used CSS to display/hide and size where needed.
Good Question
@ PlayfulWolf
I have the exact same question as you've stated here. Unfortunately, I've not seen the answer yet. While searching for an answer, I found this post by Jake Strawn that stated the following:
Unfortunately, there was no further explanation of how to accomplish it. Would love to see an example of the 'line or two of CSS' that would do this - display different layout configurations depending on the screen size like below:
Content Zone - Normal
content region - sidebar first region - sidebar second region
Content Zone - Narrow
content region - sidebar first region
sidebar second region
I have yet to see a silver
I have yet to see a silver bullet but you can move the sidebar second region below by adding #region-sidebar-second {clear: left;} to the narrow CSS and #region-sidebar-second{clear: none;} to the normal CSS. You would however have to then style the widths in the CSS for each Zone.
@3djeff To do something like
@3djeff
To do something like that, you could adjust the widths of the sidebar first and sidebar second regions in the THEMENAME-alpha-default-narrow.
For example, if you have a 12 column layout set up like this:
Content (grid-6) -- sidebar first (grid-3) -- sidebar second (grid-3)
In THEMENAME-alpha-default-narrow.css, set region-sidebar-first to have a width equal to grid-6 and set region-sidebar-second to have a width equal to grid-12.
