I too would very much like to see a fully integrated practice and testing system.

EXAMPLE EXERCISES (IN A PERFECT WORLD):

- Verb to Object matching

- Select or Fill in Collocations

- Skim and Scan (with time limit)

- Pick the Chinese character

- Pick the radical

- Write a character/Fading character

- Fill in the blank, translatiion (both L1 to L2 and L2 to L-1)

- Speaking exercises (utilizing currect voice recognition software)

- Fill in Pinyin/ Fill in Chinese Characters

- Identify and Select Grammatical Patterns from a Piece of Text

- Identify Register (IE: read a piece of text or utterance and decide if it's formal, informal, neutral, direct, indirect, personal, impersonal etc.)

- Select a Summary (IE: what answer best summarizes the passage)

- Write a Summary

- Synonym/Antonym exercises

- Register Conversion exercises (converting a piece of text or a word between registers, in other words, convert Formal to informal, colloquial, idiom, Idiomatic, etc.)

- Picture-Adjective exercises (a picture comes up on screen and we have to pick what best describes it, or type in a description)

- Video-Adjective exercies (just like pictures except with video)

- Identify the mistake

- Correct the mistake

- Teacher for a day, students explain a concept (using Chinese) like they were the teacher

- Identify Parts of Speech exercises (label a piece of text with the part of speect, EG: noun, verb, subject, object, verb, subject, predicate, co-verb, etc.)

- Reorder the sentence

- MATCH YOUR VOICE TO NATIVE SPEAKER (speak and pass only with a 90% or above phonic match)

- True/False exercies

- Consolidation exercies (consolidate a long, run-on piece of text into a shorter more concise version while keeping the meaning intact)

- Convert to Chengyu exercies (pick and/or key in a Chengyu that best matches a given phrase)

- Convert to slang/Colloquial language exercies

- Colloquial to Business conversion

- Explain or Define a Chart or Graph exercies

- Listen and Summarize

- Categorization exercies (IE: categorize the word as positive, negative, object, animate, inanimate, edible, inedible)

- Cultural Training (identify Chinese cultural and historically significant figures, events, slogans, etc.)

These exercies should also be fully integrated as testing/exerciese features in individual lessons as well as the study center.

I can think of so many more, but I think this is a good starting point and, admittedly a very tall order. Not everything can be fully implemented the way I invision it, but, at least we can have goals, dreams, visions...like I said, in a perfect world...

Oh yeah, and Popup Groups would be another feature at the very top of my wish list.
