I'm trying this out on Linux but for the life of me I can't get the split window stuff to work. The Flatpak for some reason wouldn't even open files - but the Debian package seems to work fine.
"The Flatpak cannot access your file system by default. To give it access to your documents, you must first configure that with a package like, for example, Flatseal. In case of problems, please get in contact with the Flatpak maintainer on the corresponding GitHub repository. Do not file reports on the main repository – we won't be able to help you."
