@decrek what do you think, worth exploring the concept of Block Context further or not worth the extra complexity it introduces?

[jbmoelker]

@jurgenbelien I see a project where you introduced the concept of a "theme block" as a container for multiple blocks. Is that so blocks in the same container are context aware? Would this feature solve that same issue without the need for a theme block?
