InFlow

Now you can turn any master-page text thread into an autoflow text thread in about 3 seconds. When InFlow detects overset text, it creates a new document page (instead of making you do it) and links the current text story to the autoflow text threads on the newly-created page so that text can flow automatically.

InFlow can automatically flow placed text, typed text, or text generated by other plug-ins, such as InData and InCatalog for which it was originally created.

And as a bonus, you no longer need to hold down special keys to activate InDesign's very limited autoflow capabilities when placing text--just click the loaded cursor on an autoflow frame and let InFlow do the work.
