The “Your topic is similar to…” overlay while typing a new topic is a great feature, especially for Questions, but for other topics it may be better to skip it and just show the message preview.
In particular, we have a “Jobs” category for posting job offers, and a “Showcase” category for people to show their work.
In both cases, the fact that similar topics were posted before is irrelevant. Apparently there is no setting to disable this overlay for individual topics, would you consider adding this ?
