Makagiga is available as an AppImage which means "one app = one file", which you can download and run on your Linux system while you don't need a package manager and nothing gets changed in your system. Awesome!
Makagiga™ is an open-source, easy-to-use, portable application for doing a variety of tasks, such as todo listing, text editing, or RSS reading. Plugins (add-ons) are used to implement its various capabilities.
