Todoist icon behaves differently at different resolutions
In the "New UI" (late January 2014) I've noticed that clicking on the Todoist icon has different effects in different screen formats.
When the screen is wide (two-column layout), clicking on the TD icon in the upper left corner reloads the current screen.
When the screen is narrow (one-column layout), clicking on the TD icon (now lower left corner) loads the URL www.todoist.com, and there is an extra "reload" icon in the lower right corner that behaves as the TD icon does when the screen is wider. This seems needlessly confusing, and actively unfriendly in browsers set to open a new tab for a new URL.
