 - 已软删除的 Life Post 不出现在信息流、搜索或标签筛选结果中，也不能继续编辑、评论或设置 Reaction。
 - 每条 Life Post 默认只展示评论入口与评论数量；评论列表、回复和评论输入默认折叠，用户点击后展开。
 - 已注册并完成邮箱验证的用户可以对每条 Life Post 选择一个 Reaction；普通点击默认设置 `like`，再次点击 `like` 会取消，当前为其他 Reaction 时普通点击会替换为 `like`。
-- Life Reaction 的其他类型通过右键 / context menu 打开 Popup 选择；再次选择当前 Reaction 会取消，选择其他 Reaction 会替换原 Reaction。
+- Life Reaction 的其他类型通过右键 / context menu 或可见展开按钮打开 Popup 选择；再次选择当前 Reaction 会取消，选择其他 Reaction 会替换原 Reaction。
 - 支持按 Life Post 正文搜索；用户按 Enter 或点击 Search 按钮后提交搜索，不随输入实时请求；搜索结果仍按创建时间倒序展示并分页加载。
 - Feed 顶部展示 Life 标签 Tabs，包含 All 和后台配置的 Life 标签；点击标签后按该标签筛选，搜索和标签筛选可以同时生效。
 - 信息流分页加载，初始展示最新一页，滚动到底部自动加载更多。
