Local AI Live Translate v1.2.1

What's new in 1.2.1

Fixed: lag when dragging a colour picker or slider. Every step of a drag used to send the whole config to the translation server and redraw the subtitles on the page, dozens of times a second.

• Subtitle look (colours, opacity, outline and so on): the preview in the popup follows every step. The subtitles on the page update up to 10 times a second while you drag, and once more when you close the picker or let go. None of this goes to the server any more; it never used these settings.
• Server settings (languages, model, speech tuning, API keys): sent only once they've changed and stayed the same for 0.3 s. Dragging a slider sends a single update, and typing a Qwen Cloud API key no longer restarts the connection on every keystroke.
• Server log: a repeat of the same config is no longer logged again.

To update, replace the old folder with this one, or run git pull on a clone, then reload the extension in chrome://extensions.
