It would be useful to hide items in My Library. It should be possible to see a list of hidden items in case it is necessary to make one of them visible again.
I have started to get upgrades for my 2020 marketplace items. Now I have two versions of those items showing up in My Library, cluttering it with add-ons I don’t actually want to use with MSFS 2024. For a handful of items that isn’t a problem, but I have 200+ marketplace bought add-ons. In addition there are those redundant upgrade bundles from Standard to Aviator and everything in between and then there are 2020 add-ons that I just don’t want to use with 2024 anymore. Over time it will become more difficult to stay on top of all with add-ons and their various states (filter for all of them would be useful too), and it would save a lot of time managing add-ons if the decision whether an item is still relevant could be made once.
Ideally the list of hidden items would be shared across systems. If I want to use something on PC, but not on XBox, I don’t need to hide it.
