ProTip for Ivory for Mac users: if you go into System Settings > Desktop & Dock and set ‘Double-click a window's titlebar to’ to “Do Nothing”’ then you can double click your titlebars to scroll to top. #Ivory
Actually you no longer need this tip. The code was changed so double clicking your titlebar will scroll to top always.
Ernesto@todd great! I’m glad it also has the feature of “if you already did it and scrolled to top, doing it again returns you to the place you were before scrolling to top”. I love that feature (even more important in iOS where it's more likely to be triggered by accident because it's just one tap)
Simon Harper@ernestomiquel @todd Tweetbot had that feature too. Very handy if scrolling to the top by mistake. Great to see more and more Tweetbot features making their way to Ivory.
