This is the official support thread for the Batch Editing add-on.
If you have a general support-related question, please feel free to post it here.
If you run into a bug and are familiar with GitHub, please consider filing a bug report, instead. The entry form on GitHub takes care of a lot of the troubleshooting groundwork, so it really makes it a lot easier for me to reproduce bugs and fix them.
What are the differences to the built in search and replace feature? Is it a different user interface or does it offer additional functionality?
I think it would be helpful to have that information in the description.
The information is in the add-on page. There’s a description and screenshots!
It offers some convenience features that makes it easy to add and replace field content without needing to whip out regular expressions. But yeah, as @suiyuan mentioned, there’s more info in the add-on description on AnkiWeb. I might add more of an intro to these support threads in the future, but currently short on time.
