[TYPO3-english] Multiple Content (jfmulticontent) in 7.6LTS?

[Scotty C]

Hi everyone,
Sadly, the codebase for TYPO3 is changing so fast that my favourite extensions are dropping like flies. I went through a massive pruning with the 4.5->6.2 migration, and now I'm doing it for 6.2->7.6LTS. Specifically, the extension jfmulticontent is no longer supported due to TCA incompatibilities. The error I get is:
Fatal error: Uncaught exception 'InvalidArgumentException' with message 'The way registering a wizard in TCA has changed in 6.2 and was removed in CMS 7. Please set module[name]=module_name instead of using script=path/to/script.php in your TCA. 
So, unless somebody knows how to fix this, I have to ask if anybody knows of a good alternative to Multiple Content? Its ability to handle multi columns, accordions, and sliders is fantastic.
Thanks,-Scott.
