This is actually not a good solution because it doesn’t interact usefully with the “Solved” plugin’s functions, and filtering in particular. Locked/closed topics will still show up in the “Unsolved” filter on-page. You can of course do an advanced search and filter out Closed topics from your results, but that’s less convenient and more cumbersome.
There are multiple requests for the ability to mark topics “Solved” without a reply. There are valid use cases for it:
I really think this should be reconsidered, or at least I’d like to understand why there is such opposition to doing it. In the case of requests for “mark multiple replies as solution”, I get that it would significantly complicate the plugin implementation and is not worth it. But is that the case with this more simple-seeming request? @sam I’m tagging you because I suspect this might not be seen or addressed otherwise. I apologize of that’s bad form.
