NirUI_cli --add-app GROUP NAME TYPE VALUE
NirUI_cli --add-app GROUP NAME folder "C:\Games" --recursive  # Target all exes in folder
NirUI_cli --remove-app GROUP NAME
NirUI_cli --run-group GROUP ACTION     # Actions: min, max, close, hide, show, freeze, unfreeze

# Target Types for App Groups
# process - Match by executable name (e.g., Code.exe)
# class   - Match by window class (e.g., Chrome_WidgetWin_1)
# title   - Match by exact window title
# ititle  - Match by partial title (case-insensitive)
# folder  - Match all executables in a folder (use --recursive for subfolders)

Custom Commands

NirUI extends NirCmd with compound commands in the Window Management category:

| Command | Description | |---------|-------------| | win freeze | Hide window and suspend its process | | win unfreeze | Resume process and show window |

All window commands (win min, win max, win hide, win show, win close, win freeze, win unfreeze) support the folder target type to match all executables in a directory.
