Harness.WinUI 1.1.1

Conversation width. Settings → General → Appearance lets you choose how wide the conversation gets: narrow, standard, wide or the whole window. It is wide by default (it used to be a fixed 900 px), so a big window has less empty space at the sides; a small window looks the same as before. Choose "Narrow" for about the old width.

Ask the agent to change how the app looks. "Make the conversation wider", "bigger text", "hide the usage button": it can change the text size, the conversation width and which toolbar buttons show. It asks you every time and can't change anything else (not your connection, keys or permissions).

Tips. A short tip on an empty conversation about what Harness.WinUI can do for you, one at a time. Close each one, or turn them off in Settings → General → Appearance.

對話欄寬度。 設定 → 一般 → 外觀，可以選對話欄要多寬：窄、標準、寬或整個視窗。預設是寬（以前是固定 900 px），大視窗兩側的空白變少了；小視窗看起來跟以前一樣。想要接近舊的寬度請選「窄」。

請 agent 調整外觀。 「把對話欄放寬一點」、「字大一點」、「把用量按鈕藏起來」：它可以改文字大小、對話欄寬度和工具列要顯示哪些按鈕。每次都先問你，而且不能改其他東西（連線、金鑰、權限都不行）。

小提示。 空白的新對話裡會有一則簡短的小提示，說明 Harness.WinUI 還能怎麼幫你，一次一則。可以關掉單則，或到設定 → 一般 → 外觀整個關掉。

下載後解壓縮，執行 Harness.WinUI.exe 即可。
