Great news - it's back in UE 23.00.0.59 as well I haven't checked previous builds.
As has already been posted in this thread, due to a patent claim by a third party, we were obligated to disable this functionality while the matter was investigated and resolved. We are happy to report that the patent dispute has been settled, and the functionality you miss has been restored in the following updated builds:
- UltraEdit (Windows) 23.00.0.59
- UltraEdit (Mac) 184.108.40.206
- UEStudio 16.00.0.11
For those of you who have not yet updated to this build, you can do so now by going to Help » Check for Updates.
Thanks, everyone, for your concern on this matter, and we greatly appreciate your patience. We are just as happy as you (if not more so) that the issue is resolved.
