GroupShelf groups windows from any Mac app into tabs, like browser tabs for your whole desktop. Hold Shift and drag one window onto another to make or join a group. Move or resize one window and the whole group follows. Pull a tab off to split it again, color your tabs, name your groups. Native and lightweight, for macOS 15+ on Apple Silicon and Intel. $9.99 one-time, with a 30-day free trial of every feature.
痛点：Mac 上多窗口切换和整理混乱，用户需要像浏览器标签一样把不同应用的窗口分组管理。
目标用户：经常同时打开大量窗口的 Mac 生产力用户、开发者、设计师、多任务办公人群。
证据：“GroupShelf groups windows from any Mac app into tabs, like browser tabs for your whole desktop.” 以及 “$9.99 one-time, with a 30-day free trial of every feature.”
变现：一次性买断 $9.99；可增加 Pro 版、团队授权、订阅制高级功能（云同步分组、跨设备配置）或 Mac App Store 分发。

摘要：ProductHunt 上发布 GroupShelf，把 Mac 任意应用窗口像浏览器标签一样分组，定价 $9.99 一次性买断并提供 30 天全功能试用。当前热度为 0 票，尚无用户付费或收入证据，需求真实性弱，但窗口管理/分组属于可独立开发的付费工具方向。
