I think this has been raised before, but I haven't seen the function developed as yet.
I record my weight exercises on my Garmin Epix as well as in a paper notebook. I use the standard exercise names, recording weights and reps.
Whenever I go to the gym and start on a machine I used previously, it would be good to easily know what my current preferred weight is - ideally from my watch directly, but potentially through the Garmin Connect app. I can theoretically do this by digging through the individual exercise in my history, but this is a big faff. Instead, I use my paper notebook.
It would be good to have a list of all machines I've recorded on previously, as well as a history of the weights (and reps) in a simple to access and view format. I wouldn't imagine this would be too difficult to implement.
Many thanks in advance!
