 # 할 일 및 이슈
-- 아이템 관리, 티어표 관리, 전체 티어표 관리 등에서 아이템의 이름을 관리자가 직접 수정할 수 있어야 한다.
-(사용자가 이름없이 파일을 그대로 올렸을 경우 해당 아이템을 사용 할 수 없기 때문)
 
 ## 중기 개선
 - 라이트모드/다크모드 2차 보정까지 반영했으므로, 남은 작업은 전체 화면을 실제 사용 흐름으로 돌려 보며 대비·명도·아이콘 가독성을 미세하게 QA하는 최종 테마 점검 단계로 가져간다.

+- 관리자 아이템 상세 모달은 내부 스크롤바를 숨기고 본문 스크롤이 배경으로 전파되지 않도록 body scroll lock과 ESC 닫기를 추가해, 검수 중 배경 화면이 함께 움직이던 불편을 줄임.
+- 관리자 티어표 관리에서는 `완성본 보기` 흐름을 제거하고, 전체 티어표의 추가 아이템을 클릭하면 같은 아이템 관리 모달로 열어 게임 검색·템플릿 추가·새 템플릿 생성까지 같은 문법으로 처리할 수 있게 통일함.
+- 템플릿 요청 관리의 `요청 미리보기`는 단순 썸네일이 아니라 행·열 구조, 열 이름, 배치된 아이템, 미사용 아이템까지 함께 보이는 실제 보드형 미리보기로 다시 구성해 요청 내용을 한 번에 검수할 수 있게 함.
+
 ## 2026-04-01 v1.3.39
 - 관리자 템플릿 요청 미리보기는 요청 시 저장된 보드 스냅샷이 비어 있을 경우 요청 아이템 배열을 fallback으로 사용해, 대표 썸네일만 보이는 상황을 줄이고 요청 내용을 더 안정적으로 확인할 수 있게 보정함.
 - 관리자 아이템 상세 모달에는 아이템 이름 입력과 저장 버튼을 추가해, 템플릿 아이템·사용자 업로드·보관 자산 모두 파일명과 무관하게 사람이 읽기 좋은 이름으로 다시 정리할 수 있게 함.
