This is will be a great fix if all the widgets that ships with Muse if they support 100% width & height in the next release of Muse coming by late August. Magazine websites will be born if the development team can rectify this bug in the widgets especially composition and slideshow widgets. Others are Tooltip, menu & tabbed panel widgets. Not to forget the rectangle tool that presently support 100% width and not heights.
The lack of this features has created a lot of headache for designers , others have to find and insert custom jquery fullscreen slideshows/sliders to meet client's request. Please guys you can do this. I want to launch an online magazine website by september in combination with BC, please fix this bug!
