Grep to Anchored Object has been updated to version 2.5.5.

New features and bug fixes include:

• A new option to anchor the object to the start of the current paragraph, so now there are 3 anchoring options: (1) To the end of the previous paragraph, (2) to the start of the current paragraph, and (3) in place.
• The script has been made more compatible with new versions of InDesign in cases where text-frame autosizing is used.
• Creation of anchored objects inside other anchored objects is disabled, as this often causes InDesign to crash.
• The UI has been updated to reflect the new 3 placement options.

Grep to Anchored Object is a great script for creating side-subheads (among many other uses). Click here for the main product page.
