dsh-sidebar-image-zoom

The right-sidebar image preview in dsh is deliberately static: images render at intrinsic pixel size, with no fitting or scaling to the pane and scrolling handled only by the surrounding body. That is tolerable for icons but painful for large screenshots, architecture diagrams, and data charts. dsh-sidebar-image-zoom takes over the rendering of eight image suffixes via official extension points and turns the pane into a viewport you can actually navigate.

Key interactions: mouse-wheel zoom anchored at the cursor (10 %–1200 % range), drag-to-pan with clamping so the image never escapes the visible area, double-click to toggle between fit-to-window and 1:1, toolbar buttons for fit-to-window, fit-to-width, 1:1, and step zoom, plus keyboard shortcuts (+, −, 0, 1). Images open at 1:1 by default, a live percentage readout sits in the toolbar, small images center automatically, and large images clamp panning to stay in view.

The plugin only adds an interaction layer; it does not alter how images are loaded or where they come from. All listeners, styles, observers, and object URLs are released on unmount, leaving zero residue. Uninstalling restores dsh's built-in behavior instantly since the built-in definition remains registered underneath. Ideal for developers and documentation readers who regularly inspect screenshots, design mockups, and technical charts in the dsh workspace.
