Top GTweak Alternatives for Advanced System Tweaking
GTweak is a highly functional, command-line interface (CLI) tool designed for advanced users to easily tweak various system settings. Written in batch, it offers a small footprint and allows you to enable, disable, or verify the state of system functionalities when direct shell interaction is difficult. However, its CLI-centric nature and focus on advanced users might lead some to seek GTweak alternatives that offer a more graphical interface, broader feature sets, or support for different operating systems.
