After many hours to work on it, Pure grid calendar is now scrollable.
With or without timelines.
Please, if you have a problem, report it here… not on the market.
A very common question: it is possible to change the month in the header while scrolling.
The answer is no, it is not possible.
It uses a listview, and there is now way to get a feedback of the listview position when scrolling, and it would require to redraw all the widget which is very time and CPU consuming.
This is why I display the month in cells when this is not the current month.
