Could I help users update all the extensions they installed from my extension?

I recently developed an extension called Better Extens开发者_运维知识库ion Manager to provide an alternative of Chrome's extension manager, with some improvement like search and operate on more than one extensions at one time.

Some users advise that it would be better to have a "update all extensions now" option, I couldn't find APIs from the document to do this. Am I missing something?

You might be able to do this with a NPAPI plugin but otherwise will have to open a feature request. http://new.crbug.com
