You can switch windows pretty fast with: F1 {first letter of window name} Enter. You can even add numbers in names if you like, so you can type F1 1 Enter, for example.

Do you mean that default names change after browser restarts? Yes default names are always temporary as mentioned in the help guide. It's a good point though; maybe Winger can just do without them...

I don't understand what you mean by "import windows and tabs". Please email me to discuss this further.

Edit: I'm warming to the shortcut idea :)
