Rated 4 out of 5 stars
A wish come true!
I had a pinned Gmail tab, and it ruined the cmd+1/2/3/4 shortcuts, because the Gmail tab used up cmd+1. So I'm very happy for this.
My lament: most of the time you have to click inside the panel to make keyboard shortcuts work. Could you make them work instantly?
EDIT (07/24/12): I want to let you know about a bug that the cursor arrow keys don't work inside the composing textarea, under Mac OS X. If I press a cursor key, it makes the textarea lose focus.
Thanks for the review.
I'll consider your suggestion.
EDIT (07/24/12): I'm sorry to hear that. Please contact me (alejandrosbrizuela[at]yahoo.com.ar) to see what can we do...
