Hi! Thank you for such a thoughtful suggestion — I’m really glad you’re enjoying Game Lens!
I went ahead and implemented the behavior you described, and it’ll be included in the next update.
While Game Lens is active, the existing “Toggle Overlay” shortcut will now work as a proper visibility toggle. Pressing it hides all translations, while OCR and translation continue running quietly in the background. New text won’t cause the overlays to reappear while they’re hidden — press the shortcut again, and the latest translation will appear immediately.
You’ll still be able to remap the shortcut in Settings, so you can use F9 or any other supported key combination you prefer.
One small note: I reused the existing shortcut instead of adding a brand-new one, since the resulting behavior matches your example. If you would still prefer a separate hotkey alongside the existing toggle, please let me know — I’d be happy to adjust it.
I really appreciate you taking the time to write this up. This is exactly the kind of feedback that helps make Thaluna better!
