IB have introduced a poll for new features. If you are a customer just follow the link below and vote.
My personal recommendations of most important things they could do:
1035. Include all highs and lows with each data packet (without impacting the timeliness of IBs data).
1044. Include numbers of transactions in the backfill data so that tick charts will work properly with backfilled data as well as real time data.
1078. Hoi's Time&Sales for one bar in the TWS-chart is already possible, we would like to have it through the API as well
but there are plenty of others with merit as well.
