New widgets

[Chandrias]

First of all, let me say that I like the improvements in the new Visu app.
Further to that, allow me to suggest the following:

1) I guess that the "Text input", could be also used to preview a message. 
    What I don't like here, is the limitation on the widget width (max 512).
    If you can, please allow any size.
2) I would like to have the option to draw simple shapes, in order to make
    the screen more user friendly. Just simple shapes (Line, Rectangle, Circle)
3) If possible, allow the user to split the screen in equal sections and then
    assist the placement of widgets with the use of snap points.
4) A widget to preview/edit a Scheduler
5) I really like the new "Trends" widget, nice job.
    Here I would like to be able to give another name that will appear in
    the graph (i.e. other than the actual name of the trend)
    Additionally, I would like to have the option to navigate in the graph.
    (i.e. select the date for which to see data).
6) On the "Text label" widget, I would like to have the option to define 
    a custom size for it, so I can align it with other items on the screen.
7) On the "Spinner" widget, add the option to modify the shape of the 
    buttons. (i.e. No shape, Circle, Rounded corners, Square).
8) On custom widgets, allow the use of a Compact or NonCompact mode.
