Collabora spreadsheet : creating charts and dragging formulas?

Hi All
i just manage to make CODE 2.1.4 working on my OVH server

two questions
1> i do not see any option for creating charts in the spreadsheet editor. where is that button ?

2> when i enter a formula in the first cell of a list i would be able to drag this formula all over the other cells. where is that cross mouse icon indicating the low right corner of the cell ?

i thought these features are standard in any speadsheet editor !

You have to precisely hit the lower right corner of your cell/cellblock without the big orange marker being active. The cursor will then mold into a fine crosshair and you can start dragging…
