Allow your users to reposition the pages at runtime by dragging the page
headers and dropping them into new positions. Below you can see the user
dragging the Page1 header and being presented with a set of drop indicators.
Once the user drops at the indicated right side the page is moved resulting
in the following change.
When there is more than a single cell you have more drop indicators
presented. Below you can see drop indicators for the cell the mouse is
hovering over with the bottom one highlighted. You also have edge
indicators for the entire workspace.
On dropping at the above position Page2 is moved to a new cell directly
below the Page1 cell. Use the samples provided in the download in order
to experiment for yourself.
