Yes I wish Apple would give us the ability to hide/disable individual updates from showing up in the App Store update list. There is an app that I need to use once in awhile but I can't update it to the latest version because if I do I loose the one and only feature of the app that I use. I wish Apple would change that and give us the option to hide updates.
You can also go to the App Store settings and opt to have it update automatically, so you don't have to. Lol. This if you wish to keep the app, if not yeah just delete it off your device.
