Mac 101 - Printing Envelopes

I am constantly surprised by how many people don’t know how to print envelopes with their Macs or try to figure out how to do that with Word and therefore I receive mails on a daily basis of people asking me, why Write does not offer such a feature.

Often it is even faster to simply drag-and-drop text. Yes - with your Mac you can do that. Just select (highlight) the needed text range, click into it, wait for a very short moment and drag it onto the desired text view, text field.
This even works for Safari…
Ugly, Uglier, Twitter-Icon

I guess it will become a running gag that with every new update the Twitter App will have a new and even uglier icon.
Want the old black one back?
Well, it is still available in the App Bundle - just open it and replace them. And better keep it for later…
