Hi,

We group the blocks by setting the GroupName value in ContentType attribute:

[ContentType(DisplayName = "Boo",
    GUID = "7a5b80c6-83e1-4938-8069-97d1587d54ce",
    GroupName = "Group 1")]
public class Boo : BlockData
{
}

[ContentType(DisplayName = "Foo",
    GUID = "7a5b80c6-83e1-4938-8069-97d1587d54aa",
    GroupName = "Group 2")]
public class Foo : BlockData
{
}

Is it possible to change the order of these groups in edit mode?

For example, when creating new blocks, I would like "Group 2" to be displayed before "Group 1".

Thanks!
