Plugins

Performance optimization and smoothness enhancement for DSH Desktop (renderer-side only; host code untouched, no on-disk config): skips offscreen message rendering, stops frames and timers while the window is hidden, lazily loads media, coalesces session-list repaints and pre-warms large session files; shows the measured main-thread saving in settings. A lightweight speed-up for lag, dropped frames, slow large-session opening and background CPU use.

Adds the owning workspace and current Git branch under each session row in the flat session list.

Splits the DSH main area into vertical columns, one live conversation per parallel task, with mouse-wheel paging past four columns, draggable dividers, a split toggle on every session-list row, a progress-only compact view and a one-click exit.
