Either in Cruz and Fluid there is a bug: when there are multiple tabs open and I close one it doesn't goes to the next tab but the next next tab. I would happily use Cruz but this is a major thing for me.
I'm excited for this! Open plugin architecture, greasemonkey, etc...this is the best of all worlds. Haven't gotten to give it a full spin yet, but it looks excellent. Definitely fast - thank you for creating this, it's much-needed...everyone just doesn't know it yet. ;)
