I have set up SSH access to the server of my Hostinger premium shared hosting plan, including generating a pair of SSH keys for this server. This means now I can directly access my websites' folders and files from my local machine's terminal.
Today I learned that Hostinger's Auto Installer supports not only WordPress and Woocommerce, but also Nextcloud Hub, Tiny Tiny RSS, phpBB, Kanboard, and more. Nice!
This is handy in case I do end up needing or wanting to use some of these applications.
My hobby websites' migration to Hostinger has finally completed.
