v3.4.5

Added

• Thumbnail right-click menu — right-click any floating thumbnail preview to "Close All" or "Save All to Folder…" for batch operations.

Changed

• Overlay window level raised — overlay now appears above modal panels, alerts, and security software popups (e.g. LuLu firewall).
• Enter/quick-capture defaults to clipboard — new installs default to copy-to-clipboard instead of save-to-file on Enter.
• Instant clipboard copy — clipboard copy uses lazy encoding via writeObjects, making it instant regardless of image format.
• Confirm dismisses immediately — the overlay closes before post-processing (effects/beautify), so the user can continue working sooner.
• History always saves as PNG — screenshot history uses PNG internally regardless of the configured save format, eliminating slow WebP/HEIC encodes on clipboard-only captures.

Fixed

• Save button always saves to file — the "Save" toolbar button now always saves to the configured directory, independent of the Enter/quick-capture preference.
• Save As / stamp file picker hidden behind overlay — file dialogs now appear above the overlay window (level 258).
• WebP encoding corruption — fixed broken WebP output caused by Swift-WebP's macOS encoder using wrong stride (RGB instead of RGBA) and logical size instead of pixel dimensions. Now uses the CGImage RGBA path directly.
• Floating thumbnail stuck mid-slide — fixed thumbnails getting stuck partway through their slide-in animation when taking rapid screenshots, caused by moveTo reading an in-flight animation position.
• List picker hover glitch on scroll — fixed hover highlights getting stuck on multiple rows when scrolling the language picker (or other list popovers) with the scroll wheel.
• Tool cursor shown over popovers — popovers now always show the arrow cursor instead of the active tool's cursor.
• CATransaction flush before activate — overlay windows render before app activation to prevent a flash of the deactivating app underneath.
