 ## 使用
 
 - 在桌面墙中点“添加 → 通过设备 ID 添加”，填写设备 ID、密码和可选的分组名称，再点“添加并连接”。密码仅用于本次连接，勾选“记住密码”才会通过原有凭据机制保存；不会写入桌面墙配置。
-- “添加 → 从近期连接添加”支持多选、全选和统一指定分组。导入后只加入桌面墙，使用“选择 → 连接”再发起连接。同一分组内重复设备会跳过；不指定分组时，已在桌面墙中的设备不会重复加入。
+- “添加 → 从近期连接添加”支持多选、全选和统一指定分组。已加入桌面墙的设备显示为灰色、保持勾选并标注“已添加”，不可操作，不受当前分组筛选影响；全选和待添加数量只计算尚未加入的设备，全部已添加时禁用添加按钮。导入后只加入桌面墙，使用“选择 → 连接”再发起连接。
 - 连接成功后立即记录在连接页的“最近连接”中，无需等到断开，也不要求记住密码。失败的连接不会新增最近记录。
 - “全部设备”显示保存的成员及当前活动会话。分组成员与连接相互独立：断开后成员仍在，重启后不会自动连接。
 - 卡片名称栏只显示设备名，长名称省略，不再显示状态圆点。未在线的设备（离线或在线状态未知）整张卡片使用灰色，包括预览背景、边框和名称；在线但尚未连接的设备保持正常样式。选中边框、复选框和操作入口仍可用。悬停画面可查看设备名称、ID 和在线状态，精简模式也支持。在线状态订阅包含全部分组中的设备；尚未收到结果、结果过期或服务器断连时显示未知，已有活动连接的设备仍显示在线。
