I have an app that has updates that reduce the functionality of the app. Is it possible to hide the updates so that I can use the "update all" feature, or update all apps from the list without worrying about the app? I've backed it up with Titanium Backup so I'll be able to restore it but that's a bit of a hassle. Also, the constant "New updates available" notifications are a pain in the.... neck.
Now to check for updates, you can use the Appbrain app. This gives you, a.o., the possibility to...
Additionally recommended: AppMonster Pro. Automatically creates backups of any app installed/updated. So if something breaks with an update, simply install the previous version -- and then in the Appbrain app, decide to skip this specific version. Or if you notice too late that an update removed functionality: same procedure, but in the Appbrain app decide to never update this app again.
