 - **Ctrl+Z after a scan (扫描后的 Ctrl+Z)**: after any scan, the first Ctrl+Z used to seem to do nothing: the workflow's saved fingerprints had changed, which ComfyUI counted as a step. A change of fingerprints alone no longer takes a step.
 - **Esc in a model's Outputs window (作品窗口里按 Esc)**: Esc closes the window of pictures made with a model; it used to close the model's details behind it and leave the window open.

 ### 🐢 The canvas stays smooth with other extensions (画布不再被其他插件拖慢)
 - One style rule of the browser (the list column stepping aside while a workspace is open) made every inline-style change on the page, by any extension and also while the browser is closed, restyle the whole page. Extensions that move their buttons on every canvas frame (ComfyUI-Prompt-Assistant, for one) then brought a large workflow's canvas down to 2–3 fps. The list column now follows a class on the window instead. Thanks to **@Lindemellis** for finding it, measuring it and proposing the fix ([#22](https://github.com/DemonGatanjieu/Anomalous_Model_Browser/issues/22)).
