Add more editing features to graphics
In order to make Excel for mobile a decent alternative to the desktop version, some "basic" but necessary features should be added very soon, such as:
+ the ability to edit data series linked to an existing graphic,
+ the ability to add/remove data series to an existing graphic,
+ much more editable properties for graphic elements (color, line thickness, size....)
Well, the mobile edition should be much more than a "super viewer".
