IOS – Tap to tweet/tap to post is at the bottom of the notification center

Apple does hide the settings for the drafts folder pretty well, but in general you have a choice of saving drafts on the device or on your mail server. It seems you have set them to be on the device. I suggest moving them to the server.

Here's how I get to the setting for my account. Your path might be slightly different as I think it is different for different kinds of servers:

• Settings
• Mail, Contacts, Calendars
• Under "Accounts", click on the mail account to bring up a popup with settings for that account
• Select "Account" again
• Select "Advanced"
• Under "Mailbox Behaviors" select "Drafts Mailbox"
• Under "On the Server" select the "Drafts" mailbox

I like having them on the server as then they are synced everywhere.

Apps can hook into the sharing options with the new NSSharingService API. It sounds like custom LaunchBar actions can be made with any UNIX executable file, so you could probably write a small command line tool (or you may need to build an actual app — you'll have to test it out) which activates this API (using NSSharingServiceNamePostOnTwitter), and that should display the tweet dialog.

Update: to initiate a tweet from AppleScript, you can do the following:

tell application "System Events"
    tell process "Notification Center"
        -- activate notification center
        if (count of UI elements) is 1 then click first menu bar's first menu bar item
        -- click the tweet button
        click button 1 of UI element 1 of row 2 of table 1 of scroll area 1 of window "Window"
    end tell
end tell

Furthermore, you can toggle the "Show Alerts and Banners" / do not disturb mode:

tell application "System Events"
    tell process "Notification Center"
        key down option
        click first menu bar's first menu bar item
        key up option
    end tell
end tell

(This is all very specific to the current window layout of Notification Center and is likely to break with future OS X updates — but there will probably be easy fixes.)
