 # 待测试
 
-- 配置弹窗新增“画布默认生图张数”，新建画布生图和配置节点会读取该值；模型下拉会按生图、视频、文本能力过滤可选模型，需要验证远程渠道和本地直连模型列表都能正确显示。
+- 配置弹窗改为“配置与用户偏好”并放大为可滚动弹窗；本地直连支持配置生图、视频、文本、音频四类可选模型列表和默认模型，新建画布生图和配置节点会读取“画布默认生图张数”，需要验证远程渠道和本地直连模型列表都能正确显示。
 - 画布左上角菜单和右上角状态栏新增“文档”入口，会使用 `NEXT_PUBLIC_DOC_URL` 配置的地址并在新标签打开文档站；需要验证登录和未登录状态下顶部入口都可见。
 - 文档站搜索改为中英文混合 tokenizer，中文正文、标题和短语会按中文词、单字、二元和三元片段建立索引；需要验证 `/api/search` 和搜索弹窗能命中文档中的中文关键词。
 - 文档站改为 Next.js standalone server 输出，新增 `docs/Dockerfile`、`docs/docker-compose.yml` 和 `docs/docker-compose.local.yml` 独立运行入口；需要验证文档页、搜索接口和 LLM 文本接口在文档站容器中可访问。
