TextPlus

I have been using TextPlus for word, phrase completion and found in trying Instant Text Mobile that common words like "write" aren't in the glossary but I get words like worrying and worthwhile. I wondered if you had a glossary with more of the common words. Also is it possible to have both products active at the same time? One more question - how do you return to the app you were using after adding an entry to the glossary?
