Tips: drag the splitters between the media library, preview and timeline to resize them (double-click a splitter to reset). Use the panel button to detach a panel into a floating window, then drag its header to move it. In the media library click to select, Ctrl/⌘ click to multi-select and Shift click for a range; selected items can be added in sequence or removed together. In the preview, drag a selected clip to reposition it and drag a corner handle to resize it — the size and position are saved with the clip. Right-click any clip, media item, track header or the preview for quick actions. Drag a split piece against its sibling and the clips merge automatically on drop; the context menu can also merge them manually. Color & effects include blur, grayscale, invert, vignette, glow, blend modes, pan and high/low-pass audio filters. A opens the asset studio, T manages timeline tracks. Drafts and media are stored in IndexedDB; only export preferences and the panel layout use localStorage.
