vtiger is becoming more and more stable, except for some minor issues with installations and configurations. Hopefully these will be fixed before the final release. On the UI front I am planning to take up some measures to ensure clutter free code and better UI experience. After 5.0.0 most of the focus was spent towards stabilizing the product. I think its the right time to tinker the user interface as well. Not sure, if it is right to get into the product at RC stage. But anyway, expect some improvements soon. 🙂
