I've found following bugs during testing In-Portal 5.2.1-B1 install one a new project:

When adding administrator in "Users Management -> Administrators" section window title shows "Add User" instead of "Add Administrator". Suspect that "User" word is all over that section phrases instead of "Administrator" word.
After clean install category permission cache missing that results in all theme-related sections missing from "Structure & Data" section. That's why I need to use "Rebuild Section Cache" menu in that section to start working with "Structure & Data" section.
Section "System Log", that was added under "System Logs" is visible in "simple" interface preset, but we have a rule, that all new sections are hidden by "simple" interface preset by default.
