# 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)

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.
