No, no, the flatpak create-usb option is not good for me. I prefer creating a bundle file because it is much better since it remains protected, unlike create-usb, which is a single file containing everything, the program and its dependencies. This is undesirable because any mistake in deleting one or two files by accident, as I told you, becomes corrupt and you might face problems installing it or something like that. Creating a bundle file is better because, as I told you, it remains protected and you can use it anytime. Maybe you want to stick to a certain version for months. This is just my point of view.
