Kentico 8’s Admin UI control is pretty flexible – you can easily add pages to any part of the admin area. Here’s a quick walk through on how you can add a tab to the content area and make sure it only displays for a specific page type.
If you’re using roles and the staging module in Kentico, a change to the role record will not only push through that record, but will synchronise the related user-role entries as well. Once the role has been staged, your user-roles on the destination environment will be the same as on the source (users will be added or removed from the role). Depending on how you’re using staging with your environments, this may not be desired behaviour. This article explores one way to manage this – how you can exclude roles from being staged (or other objects!), without affecting any other staging settings.
