I do agree for the synchronization. This must be useful and efficient resources.
Another think, if may request, will be good if it can be a native apps.
I really like when I have a schedule for what ever, it reminds me with a pop-up on my phone screen.
And if there is new assign task, or updates, it could be cool if it can be pop-up to the screen.
This will be very usefull application in term of the way to be productive.
Best Regards..
