[x] It seems that the 'Alert' type and 'danger, warning, info, success' div stylings in the additional theme are not well fitting, the divs are fully opaque in one color (no shading or other 'nice' visual stuff) and the text is then also styled in the same color and therefore invisible.
for the alert (warning, danger .. etc) CSS selectors the background color is the same as the color!
[x] also it happs that the popover tooltips seem to push the text/input fields around in the metadata editor
