App pages - Generic questions

Product: PowerShell Universal
Version: 4.0.1

Just upgraded our test instance to 4.0.1, and have a few questions regarding the pages in Apps.

  1. If you create a new page and select “Use Designer”, the Delete button is then missing = you cant delete the page from the UI. Is this a brainfart from my side, or a bug?

  2. Is there a way to generically load all pages in the App / Dashboard, instead of having to manually specify them like this:

$Pages = @()
$Pages += New-UDPage -Name 'Home' -Content {
    New-UDGrid -Container -Content {
$Pages += Get-UDPage -Name "O365 - Mailbox Management"
$Pages += Get-UDPage -Name "AD - User Mgmt"
$Pages += Get-UDPage -Name "AD - Group Mgmt"

New-UDApp -Title "Test toolbox" -Pages $pages -Navigation $Navigation -NavigationLayout Permanent 

I have come for this answer, anyone know how to delete a page created with designer?
