If you want a SVG editor the you can test this web tool from here.
The web tool named SVG-edit is a fast, web-based, javascript-driven SVG drawing editor that works in any modern browser.
Is more simple like Inkscape and can be used online.
Also you can download it and test it like stand alone tool .
I try to use Export and Save Image , but seem not work with Opera browser.
I solve this issue with key U - Apply Changes and then with Copy - Paste into new SVG file.
