🚀 v1.1.37 更新内容
🐛 问题修复
- 远程媒体播放卡顿 / 拖动跳回原点：重构本地 HTTP 流式代理的 seek 缓存与分块填充，修复非零偏移区域读取 bug；拖动后首字节延迟由整段 24MB 降为首个分块，SFTP/SMB/FTP 拖动不再跳回原点。
- SFTP 上传限速约 2MB/s：升级 JSch 0.1.55 → 2.28.7 以支持 rsa-sha2/ED25519/OpenSSH-v1 密钥，避免静默回退到纯 Dart 的 dartssh2（限速根因）；setBulkRequests(128) 提升在途请求数。
- SFTP 符号链接目录（如 /sdcard）识别：列表时跟随符号链接真实目标类型，目录可正常进入。
- 编译错误（进度最小化状态机）：字段初始化器引用实例方法导致编译失败，改为构造函数体内赋值并放宽 final。
✨ 新功能 / 功能优化
- 双窗口激活窗口顶部高亮：激活窗口的整个顶部状态栏高亮（primary 背景 + 2.5px 高亮边），更易识别。
- 进度后台最小化为浮窗：复制/剪切与分类页备份进度点「后台」后，在状态栏/工具栏显示可点击的圆形浮窗按钮（带旋转进度环），点击重开进度页；传输完成/取消后自动消失。
- 远程 Tab 云图标：远程浏览页 Tab 左侧图标直接用云图标替换原文件夹图标，本地 Tab 仍为文件夹图标。
- 文件类型图标优化：未获取媒体缩略图时，图片/视频/音频/安装包显示「类型图标 + 格式标签」（MP4/MKV/MP3/FLAC/APK 等）；安装包用安卓机器人图标（绿色），压缩包用捆绑包图标（Broken.box）并显示 ZIP/7Z/RAR 格式；分类页音乐页音乐图标下方也显示格式标签；浏览页与分类页图标显示一致。
- 远程缩略图缓存隐私保护：远程媒体缩略图缓存迁入 .nomedia 目录并写入标记文件，避免被系统媒体库/其他文件管理器索引；默认远程缓存自动清理间隔改为 0（不自动清理）。
🎨 性能优化
- 远程媒体流式代理调优：多段独立 seek 缓存（上限 4 段）避免来回拖动反复缓冲；mpv 缓冲参数放大（cache-secs 60 / demuxer-max-bytes 300M）减少周期卡顿；引导预取 16MB、按需抓取 24MB 提升起播与拖动跟手度。
🚀 What's New in v1.1.37
🐛 Bug Fixes
- Remote media playback stutter / seek jumps to start: rebuilt the local HTTP streaming proxy's seek cache and chunked prefetch; fixed a non-zero-region read offset bug so first-byte latency dropped from "whole 24 MB segment" to "first chunk". Dragging no longer jumps back to the start on SFTP/SMB/FTP.
- SFTP upload capped at ~2MB/s: upgraded JSch 0.1.55 to 2.28.7 to support rsa-sha2/ED25519/OpenSSH-v1 keys, eliminating the silent fallback to the pure-Dart dartssh2 (the root cause of the cap); setBulkRequests(128) raises in-flight requests.
- SFTP symlink directory (e.g. /sdcard) recognition: follow the symlink's real target type on listing so directories can be entered normally.
- Compile error (progress-minimize state machine): a field initializer referencing an instance method failed to compile; moved the assignment into the constructor body and relaxed final.
✨ New Features / Improvements
- Split-pane active window top highlight: the entire top status bar of the active pane is highlighted (primary background + 2.5px accent edge) for clearer identification.
- Progress minimized to floating widget: after tapping "background" on copy/move or category backup progress, a clickable circular floating button (with a spinning progress ring) appears in the status/tool bar; tap to reopen the progress page; it auto-dismisses when transfer completes/cancels.
- Remote tab cloud icon: the left icon of a remote tab is now a cloud icon replacing the folder icon; local tabs keep the folder icon.
- File-type icon polish: when no media thumbnail is available, images/videos/audio/install-packages show a "type icon + format label" (MP4/MKV/MP3/FLAC/APK...); install packages use the Android-robot icon (green), archives use a bundle icon (Broken.box) with ZIP/7Z/RAR labels; the music category page also shows a format label under each music icon; browsing and category pages share consistent icons.
- Remote thumbnail privacy: remote media thumbnails moved into a .nomedia directory with a marker file so they are not indexed by the system media library / other file managers; default remote-cache auto-clean interval changed to 0 (disabled).
🎨 Performance
- Remote media streaming proxy tuning: multi-region seek cache (max 4 regions) avoids re-buffering on back-and-forth seeks; enlarged mpv buffering (cache-secs 60 / demuxer-max-bytes 300M) reduces periodic stutter; 16 MB prefetch and 24 MB on-demand fetch improve start-up and seek responsiveness.
