dropping link button on same collection makes a pushpin. fixed broken undo typing to crate doc in sidebar. fixed min/max scaling for cropped images and made annotationOverlays start to use it. Fixed nested text boxes to stopPropagation on pointer down to enable editing of translations in sidebar. moved sidebar filters onto doc's filters. Added metadata filters back to sidebar. Added an -any- option to filtersPanel. fixed schema view preview window, added buttons and sliders.
