Hello navuho,
If you want to make your main container being wider, also you will have to change the width of the theme and please notice that our product does not have such an option for dynamic width and we do not recommend to do that through the custom CSS code because the layout of the theme will be damaged. If you want to change the width of the theme to be in full-width mode, please notice that is not a simple task and you will have to adjust the entire theme to the new width for better results.
For your second request, yes from there you can change the thumbs size but please notice that is not a simple task and if you are not aware of the further steps in this regard, you can break the layout of theme.
If you want to display more levels in our theme and you are not aware of the steps in this regard, please consider hiring a freelancer/developer to do this for you because we cannot provide customization services at the moment, sorry!
Thanks for your understanding!
Hello navuho,
Unfortunately, I cannot provide you an accurate response in this regard because please keep in mind that this task is very complex and also, is very difficult to do. Below, I gave you a simple example, like this ->
Try to simply increase the width of the main container .td-conatainer and you will see that the Big Grids will be damaged, like this -> http://screencast.com/t/eY1j45pC Please understand that all of the theme elements were been designed and created on width FIX and if you will increase this, practically you will have to make a new theme from scratch because each element will be deteriorated.
Thanks for your understanding!
