I drop a TTMSFNCStatusBar, add 3 panels to it, set all 3 with an alignment taRightJustify, panel 1 and 2 appear still left, and only panel 3 appears on the right, where it should be.
When I set each to taRightJustify, they all should appear on the right side, not on the left. This seems to be a bug.
There is currently unfortunately not a setting for this. Panels lign up from the left. We'll consider adding support for putting panels also at the right side.
