Hi,
If the new Gantt chart is a lot better, there is a key issue: it doesn't keep the configuration made.
Indeed if I'm adding a grouping, it won't stay. I'll have to set it again next time.
Configuration should be either stored at any change, or saveable.
As such it is not really user-friendly, and make it hard to get used by users who are not using daily Wrike, what decreases its value (still we need to make Gantt Charts out of Wrike).
