I wanted a way to braindump my todos in the same terminal while using Claude Code. This sidebar plugin lives in a tmux split pane and lets me queue up tasks without interrupting Claude's flow. Add tasks while Claude is working, reference them when needed, and they persist across sessions—so your todo list is still there when you restart Claude Code. It keeps a running log of everything you've done, and Claude Code is aware of the sidebar's existence so you can reference tasks directly in conversation. Still a work in progress, but I use it daily and find it genuinely useful for staying organized during longer coding sessions.
