The "Help" button in the page should be a "?" icon right next to the "X" aka close button in the upper right, it is more intuitive and feels less out of place.
Transferring to UX team to decide.
History suggests issue is in the BASIC toolset, but this report is close to useless. Unable to locate the GUI component requiring suggested enhancement. Please clearly identify the element, screen clip(s) perhaps, and provide steps to reproduce the issue.
Ignore the previous comment. So… The Help button is there because LibreOffice runs in multiple platforms. Windows is the only OS which provided support for a “?” button in the title bar, but that has been deprecated for long already. As OS X and every Linux window manager I know don’t support it, we place our help buttons in the window area. Which I think it’s fine.
