There is an open bug report for it. Seems like it might be brought back from what I have read on there. https://bugs.kde.org/show_bug.cgi?id=481069. Someone has commented having already re-implemented the feature, but they seem to be stuck on something. If you can perhaps consider helping them out.
I wouldn’t say no issues, but nothing like what some people are complaining about. I only have one major issue in my opinion.
