• psmux-git-status — Git status in status bar
• psmux-continuum — Auto save/restore sessions
• psmux-resurrect — Session persistence

Linux/WSL — tmux (declared in config/.tmux.conf, installed via tpm):

• tmux-prefix-highlight — Visual prefix indicator
• tmux-continuum — Auto save/restore sessions
• tmux-resurrect — Session persistence

Key Bindings

All prefixed with Ctrl+b unless noted (same on both platforms):

Key	Action
e	Reload config
P	Reload shell profile
|	Split pane horizontally
-	Split pane vertically
Shift+←/→	Previous/next window (no prefix)
< / >	Move current window left/right
s	Fuzzy switch session (fzf)
w	Fuzzy switch window (fzf)
g	Fuzzy switch pane (fzf)
/	Search scrollback
r	Fuzzy find & replace across files (fzf)

Neovim

Config is config/init.lua (Lua). Uses lazy.nvim for plugin management.

Plugins: Gruvbox theme (dark, hard contrast) · Telescope (fuzzy finder) · Rustaceanvim (Rust LSP, code actions, debugging) · nvim-treesitter (syntax highlighting) · C# LSP via roslyn.nvim (Roslyn language server)

Note: roslyn.nvim requires Neovim ≥ 0.12 and the .NET SDK. The Roslyn server is installed as a global dotnet tool (roslyn-language-server) by install-roslyn.ps1 / .sh.

Config Files

File	Windows Destination	Linux Destination
config/.psmux.conf	~/.psmux.conf	—
config/.tmux.conf	—	~/.tmux.conf
config/init.lua	~/AppData/Local/nvim/init.lua	~/.config/nvim/init.lua
config/.ripgreprc	~/.ripgreprc	~/.ripgreprc

Making Changes

This setup is incremental — edit configs or add plugins in the repo, then re-run:

.\setup.ps1          # Windows

./setup.sh           # Linux / WSL

• Install scripts skip already-installed tools
• Config files are synced (repo → home) on every run
• New plugins are installed automatically
