👑[Enhancement] 关于Watt Toolkit 3.0 的一点建议

原来2.0+版本的字体十分舒适，但3.0让我有些不太习惯。
希望能将字体**略微放大**，并**增加抗锯齿或提高分辨率。**

让我**惊喜**的功能是插件商店，虽然现阶段没有放出，但我已经十分期待了。
希望能自己导入插件或从Git仓库直接下载导入。
最后希望 Watt Toolkit 能真正成为游戏玩家一站式工具。

No files or tests are named, and the issue combines typography changes with plugin importing and broader product goals. First clarify which suggestion is in scope, then locate the relevant Watt Toolkit 3.0 UI or plugin-store entry points. Done should be defined as an agreed, testable change rather than the full set of proposals.
