Subject line says it mostly. Normally, when you click a bookmark button it replaces the content in current window by default. I am aware I can hold CTRL or SHIFT down to launch a new tab or window respectively. I would however like to be able for certain bookmarks to set the default launch behavior, similar to setting the HTML target=_blank tag on a link. I need certain bookmarks to always launch into new windows (and even nicer would be to launch into a conveniently resized window to left or right of my current window). The idea is that there are frequently times when the content of both windows is needed at same time.
