The LEM/SEM interface had a feature where one could great a filter in "Live Events' and then end it over to "Historic Events" aka nDepth for historic analysis. This feature is no longer available since the Flash to HTML5 migration. It has not been migrated as of 2023.2. I opened a ticket on this issue which as closed. I was told it is on the roadmap. This is very disappointing because this is a critical feature when hunting down historic event. Once can always recreate the filter but shouldn't have to duplicate work.
