as the heading says:
is this is good idea? could libreoffice have a tab on its draw program that previews .svg images in firefox (if installed)
I think it might be a good idea, because svg files can include js that build part of the image when it is loaded, so it might be nice to preview how the modifications effect the svg file w/o needing to switch programs at each edit.
(another idea might be if something like draw or inkscape, be implemented as a third tab to a program like aptana so it has: manual source editing, draw visually, and preview - that would be a plus for aptana.)
