> [!Important] > **Developer Note** > This code change will **completely move gumps out of the core** ### Summary - Adds `GetGumps()` convenience which exposes methods to Find/Close/Send multiple gumps. This helper is a performance improvement by eliminating the Dictionary<Player, List> lookup for gumps.
