液态玻璃功能波：材质预设 + 壁纸采样渲染 + 一轮性能与手感打磨。

新功能

液态玻璃材质预设（8 种）：亚克力 / 亚克力·薄 / 磨砂哑光 / 烟雾 / 毛玻璃 / 清透玻璃 / 液态玻璃 / 深色玻璃。选中即套用整套背板配方（背板类型、颗粒、着色参数），与颜色预设互不干扰；后续版本改为显式开关（勾选用配方、取消即自定义），并新增「默认」材质——没动过材质就默认勾选「默认」，画面零变化
壁纸采样渲染（新渲染方案）：背板改为「采样当前壁纸 + 自行模糊」，设置 → 外观可开关。模糊半径变成真实像素，材质预设全部生效；自动适配 Wallpaper Engine / Lively / 火萤等动态壁纸软件（图片类读原文件、场景类抓当前画面），1:1 物理像素采样，多显示器各铺各的壁纸；壁纸换了点「重新采样」即可刷新
便签「固定位置打开」：快捷键唤出便签时可选择按原位置打开（默认关，即原位置），不再强制居中

液态玻璃采样全面修正：按物理像素 1:1 采样，照片/视频壁纸不再发糊、不再区域偏移；重新采样后各窗口立即刷新；DWM 方案下材质不再吞掉着色、失败路径不再留一块不透明背板；抓屏时玻璃窗口短暂让开，设置窗口不再被采进背板
窗口标题栏内联改名：改完名字即时生效并同步到设置界面各处（分区 / 组合分区 / 便签）；「点别处」「停手」「关窗」也都会提交改名，不再出现标题框是新名字、配置里还是旧名的情况
打开窗口先展开再动画，不再先闪一帧空框
次级分区浮层：去掉图标选中高光描边；回收站右键菜单补上「清空回收站」；回收站被收进次级分区后图标状态也能正常刷新
默认网格大小 56 → 65，与分区默认值一致

Liquid glass wave: material presets + wallpaper-sampling rendering, plus a round of performance and feel polish.

Liquid glass material presets (8): Acrylic / Thin Acrylic / Frosted Matte / Smoke / Frosted Glass / Clear Glass / Liquid Glass / Dark Glass. Selecting one applies a whole backdrop recipe (backdrop type, grain, tint parameters) without touching your color preset; later refined into an explicit toggle (checked = apply recipe, unchecked = custom) with a new "Default" material — untouched material now starts checked on "Default" with zero visual change
Wallpaper sampling rendering (new renderer): the backdrop is now "sample the current wallpaper + blur it ourselves", switchable under Settings → Appearance. The blur radius becomes real pixels and material presets take full effect; auto-adapts to dynamic wallpaper apps such as Wallpaper Engine / Lively / Firefly (image wallpapers are read from the file, scene wallpapers captured from the current frame), samples at native 1:1 physical pixels, and lays out each monitor's own wallpaper; hit "Resample" after changing the wallpaper to refresh
Sticky note "open at fixed position": optionally summon a note at its current position via hotkey (default off = last position) instead of forcing it to the screen center

Wallpaper sampling accuracy fixed across the board: 1:1 physical-pixel sampling — photo/video wallpapers are no longer blurry or region-shifted; windows refresh immediately after resampling; under the DWM scheme the material no longer swallows tinting and failed paths no longer leave an opaque backdrop; glass windows briefly step aside during screen capture so the settings window is never sampled into the backdrop
Inline renaming in window title bars: renames apply instantly and sync everywhere in the management UI (zones / merged groups / sticky notes); clicking elsewhere, pausing or closing the window also commits the rename — no more "new name in the title box, old name in the config"
Windows now expand with animation from the first frame — no more flashing an empty frame first
Subfolder flyout: removed the highlight outline on selected icons; the recycle-bin context menu gained "Empty Recycle Bin"; recycle-bin icon state now refreshes even when the bin lives inside a subfolder
Default grid size 56 → 65, matching the zone default

Dragging the blur slider no longer stutters: large-radius pre-blur now runs at half/quarter resolution (≈7× faster at radius ≥ 20) with quantized cached steps — per step, up from 1.6 s down to ~30 ms
Glass rendering overhead reduced: no probing screen capture at startup, throttled wallpaper detection, LRU eviction for the blur cache, and automatic resampling after display changes
Leak cleanup: closing windows no longer leaks visual trees, property-panel field trees no longer leak on rebuild, icon cache is capped, panel position saving is debounced
Panel edits no longer apply styles twice (background image decoding is cached); startup no longer scans desktop shortcuts synchronously (missing-icon recovery now runs at idle)
