As for removing links/content from the app, there's no reason an update couldn't provide access to this while "offline" from the WIU/MTH-mode;
I don't know if I would try to make that much information available offline, the data storage requirement for it would be pretty massive especially if you are to include Parts diagrams, item descriptions. I scrapped the MTH website about a year ago and there is a lot of data on it.
I like the idea of integrating some of the online social media elements to help entice a younger generation but also I'm also weary of bloating an app with too much stuff that can cause other problems or unexplained crashes. The KISS method has always been a good approach.
No don't be ripping on Wordperfect! I think dad has mastered the 1989 DOS version 5.1and now I'm thinking he's ready for a jump to a Windows version!
