Promotiom

I cant say anything without detailed info:

I think this is only happens when you choose Front page displays as A static page from Static Front Page but you didnt select a page for home page. If this is not the case, i am pretty sure there is another problem with your installation so i can suggest to try with a fresh wordpress install

I am pretty sure there is no problem with Before Content promotion bar but i am glad problem is gone now

There is a statement in top of those options:
These settings will activate when you save changes and refresh this page.

PromotionBar will not show if you choose Only Content as Layout and In top of Sidebar for Which location do you want to show Promotion Bar?. Basically you are not showing sidebars.. How can you expect promotionbar will show in sidebars while there is no sidebar showing?

System will show it as slide if you have more then 3 post in it.

Currently bootstrap dont have other transitions so i am waiting for bootstrap 3.0 release then we will see. (so maybe in future)

Fixed sizes are a bit complicated because of lots of possibility for contents. Somes are short texts, others are images or videos. After WordPress 3.6 release, i will check possibility again.
