WorldServer QA feature

Hi Team, 

I just wanted to check in the new version, can we have below features? 

Can export the file WS file into Excel, .CSV, HTML, WORD, PPT?

Can we import the files in WS after completing the QA? 

Can we see the track changes in WS rather then checking flags in reviewed strings?

Can we have Plug ins for any QA like Xbench?
