While it's unclear what Maka stands for, the "giga" part of Makagiga most likely refers to the number of tools this application has on offer. It comes with a to-do manager, RSS reader, a basic photo viewer/editor, a text editor, miscellaneous widgets, and much more. Makagiga is written in Java, so it runs on any platform with Java Runtime Environment.
Integrating disparate tools into a single application without making things confusing can be a challenge, but Makagiga tackles it well. The application's interface is divided into two panes. The left pane contains four default root folders: Files and Folders, Feeds, Find Files, and Trash. You can view the contents of each folder as a hierarchical tree by clicking on it.
When you select an item in a folder, its contents are displayed in the right pane with a context-sensitive toolbar.
