chat-pace: Advanced Auto-Scroll Control for DeepSeek Harness

The DeepSeek Harness (DSH) plugin chat-pace is designed to address the readability issues caused by agents outputting long text too quickly. It offers five scrolling modes (smooth, segmented, manual, among others) and global hotkeys, working together with DSH's built-in follow logic to let users regain control over the reading pace. The plugin features session position memory, persistent settings, and debugging functionality, automatically switching control based on user manual operations to maintain a balance between careful reading and automatic updates.
