the annotation toolbar on the left has a fixed height and is vertically centered if the viewport height is smaller than the toolbar height (e.g. hosted in IFrame or small browser window).
This results in a cutoff toolbar (top and bottom) where you cannot choose the upper and lower annotation tools any more and where you are not able to move the toolbar somewhere else, because you cannot reach the upper side of the toolbar (it’s cut off) - even on resize (no vertical recenter on resize (enlarge)).
This should be changed to a toolbar with responsive design that adapts to its viewport (2nd column or scrollbar).
Many thanks in advance!
Thank you Pavel,
works like a charm!
