Engineering has restored search of extension code rather than the title.
This is extremely valuable! For example, say you have many extensions, and you need to identify which extensions actually make utag.view() calls (or some other pixel-specific code), or maybe such calls that include a specific Data Layer variable - especially if you have renamed that variable, because while mappings in the associated tag will update, your Extension code will not. If you can't search the code, you have to open each individually.
Another scenario, we have multiple extensions, for different pxiels, that read the same cookie. Being able to locate that cookie name via a search, even with Labels applied, helps filter down to just the extensions using that cookie.
