Ubunsys, which is under active development and not yet considered stable, exposes various advanced security, package management and system settings in a straightforward wizard-style UI.
Or to put it another way, it lets you quickly and easily toggle on/off, enable/disable and add/remove some core features of Ubuntu by clicking buttons rather than running commands or using different apps.
Because Ubunsys makes it really easy to toggle, check and do things you ought not to do on your system it’s a tool best suited to advanced users who know what they’re doing.
