This is a great tool, thanks for the continued support.
Personally, I don't actually use dockcheck to perform updates, I only use it for its update check functionality, along with a custom plugin which, in cooperation with a python script of mine, serves a REST API that lists all containers on all of my systems with available updates. That then gets pulled into homepage using their custom API function to make something like this: https://imgur.com/a/tAaJ6xf
So at a glance I can see any containers that have updates available, then I can hop into Dockge to actually apply them on my own schedule.
I'd like to know the same. I really like the RP2040 and use it often, looking to move to the RP2350 but the GPIO issue is holding me back.
