I use Instagantt integrated to Asana, where I can set date ranges for each task.
When I come back to Asana and use the Calendar view, it only show the due dates.
It would be great to use colored regions to show time ranges of a task, as it works on Google or Apple calendars.
When you’re planning a project you always need to see how long each task take, and this is with date ranges.
Instagantt works great on this but has the same limitation (I also left this same feedback for them).
Well, and if you’re able to add a Gantt and Workload charts inside Asana, chapeau!
