Is there a GUI frontend for the snap command? I will never remember all those options and don't like to have a tattered printout of the help for reference.
Meanwhile, for immediate problems, what command do I type for checking for updates and upgrades?
There is no GUI. It's not deliberate, but it's also not viewed as neccesary.
Snapd checks for new versions four times each day, and automatically downloads them. The completely-automatic method is a key feature of snaps. If you want snapd to check now, run sudo snap refresh
While it is possible for you to specify a version of snap to run, it's deliberately not a front-and-center feature for users. Developers generally want everybody to run the same version; it's much easier to support that. If you really want to run a previous version, run sudo snap revert package_name --revision XXXX
Note that it's revision number, not version number. Run snap list to see the current revision (and version) numbers for each of your snaps. Snapd is designed to hold at least one older revision (often two older). Revision numbers increment by 1, so it's easy to determine what older revisions you can try.
In my experience with Linux, and as of Jul 2 - 2023, there is GUI for non-Ubuntu Linux distributions (at least the ones that I have installed), but for the latest LTS and for the latest regular releases of Ubuntu itself there is no separate GUI available, as all the software (snap or Debian) are supposed to be displayed together in the Ubuntu Software app.

Actually there is a Frontend, works for me on Kubuntu, for i use german language it shows in the menue as "Anwendungszentrum" i do not know whats its name in English, but it has an Orange icon install it with
sudo snap install snap-store
Simple but working, i still do updates on commandline so i dont know if the update function works but i guess so because it is no 3rd party software.
