meh, i'm prob gonna use silver lining, but i like ninja and cold shower too.
for the themes, go to settings, then on the top where the "tabs" are (general, accounts, labels, filters, etc...), the last one is themes.
yer terminal theme looks great also contrast was good, but i applaud the person who made terminal.I love the terminal theme (if only they would swap out the check boxes for ascii and use javascript it would be perfect)
No the last one is "labs" for me. Mine is like:
"Settings
General
Accounts
Labels
Filters
Forwarding and POP/IMAP
Chat
Web Clips
Labs"
