I have found that the new thin client acts slightly differently from the old web client. In the old web client, I can configure it to not show items. This results in the item master not being displayed. In the new thin client, I have done the same, but I still see the item master folder. I am told that this is because I have item permissions (logging in as an administrator). So, I can fix this for the general user population, but not for the admins. I would respectfully request a change be made so that the item master folder not be shown even though you have the administrator role.
Thanks,
Mark
