h3028: The rebar was removed when adding the customisable toolbar and removing the multiple original ones - it didn't seem to have a lot of purpose any more and added a lot of code. PN tries to balance speed and simplicity against powerful features, and retaining the rebar just to support the single scenario of toolbar on the same row as the menu didn't seem worthwhile.
That being said, if there's significant compaint about it being missing then I'll put it back. Sadly the lack of icons in the menus is a side-effect of this change, they will come back but more code is needed :)
The black toolbar icons in the mini-toolbar will be resolved before the next release, and I intend to allow you to hide that toolbar and add the buttons to the main toolbar.
