1. It shows only the last selected object, not the entire selection.
So to preview a whole icon made of several objects, i have to group
them and select the view. Very inconvenient.
2. There must be some way to set the background color of the dialog.
The perception of an icon changes a lot with different backgrounds,
and it would be nice to be able to preview different backgrounds in
the dialog, without changing the document.
3. Please provide at least the size labels for the buttons.
4. Please make it auto updating on selection changes and
modifications, without having to press Update.
