Hello Andres,
Thank you for the great suggestion!
I just did a hotfix to edit the Slam-it toolbar. Delete your old one and then install (drag) the new one from your dashboard.
You can adjust the horizontal placement as follows:
1. Edit the bookmark.
2. Notice that the URL is about 300 characters of Javascript.
3. Look for the text "screenLeft+100".
4. Change the '100' to whatever you like.
5. Save the bookmark and try it out.
Please let me know if that works. How many pixels does your monitor have?
