I will agree that there is really no room on the n800 for extra tool bars in the browser. It would still be nice to be able to Stumble. I wish I had the skill to take Stumbleupon apaart and create an N800 version. Maybe just a single button in the dropdown menu. Or maybe use a direction on the D-pad to stumble. That doesn't include a solution for thumb's up or down, but it would be enough for me.
