Orbitiny Desktop can be downloaded from SourceForge.net.
Source code is hosted on Gitea.com: https://gitea.com/sasko.usinov/orbitiny-desktop
Note: Orbitiny can be run in portable mode (no installation required) or can be installed to any directory. To run it in portable mode, just launch the start-orbitiny script. In portable mode, all the settings will be saved in the directory the start-orbitiny script is in. You can then copy this folder to a USB stick, take it with you, go to another Linux computer and launch the script again and all the settings and configurations will still be there.
To install it system-wide and be accessible from your Display Manager’s menu, just run the graphical install-orbitiny script using sudo.
As a system-wide desktop (non-portable mode), the settings will be saved to $HOME/.config/orbitiny for each user.
