There is such functionality but it is disabled by default. To enable it you should:
1. Go to User Options
2. Select General Tab
3. Check Auto list members option
Please keep in mind that Auto completion is not as usable as we wish to be. In order to improve its state, we would definitely need your feedback. It will be great if you could tell us if anything is wrong, missing or could be improved.
Thank you very much for using Icenium!
