StatBlockCore is a display addon for LibDataBroker plugins.
SBC offers a variety of options some plugin based, some global based. It's main goal is to provide freely movable blocks based on the LDB system, whilst keeping to a minimal codebase.
Also a lot of other addons are using LDB for their quicklaunchers, SBC fully supports them.
Examples of plugins are:

SBC does nothing on it's own, it needs LibDataBroker plugins to function. You can find these in the Data Broker section.
