Glad to see a new version of EmEditor with some useful new features. Bit disappointed though that my suggestion for text extraction has still not made it in though, particularly given that EmEditor already has a lot of the functionality needed to implement this feature:
I am not exactly sure what you would like to see in future versions. If you want to extract searched lines, you can “bookmark” searched lines (by pressing the “Bookmark All” button in the Find dialog), and then use the “Extract Bookmarked Lines to New File” command. You can also write a macro to automate this process.
