Actually you can Alt (Option) click that icon to enable Do Not Disturb without actually opening the notifications center :).

Mac pro tip: Option-click everything. It's remarkable how many secrets are lurking behind near every UI element.

And once you've option-clicked, also option-shift-click, command-click, control-click, etc.

An easy favourite is the Wifi menu bar item. Option-click to see all sorts of useful info about your current connection, including IP address, MAC address, connection speed (Tx Rate), the amount of noise, etc. And when you've option-clicked the menu, hovering over network names shows you the key info about that network.

Yeah, pretty much every icon in the menu bar has an Option-click alternative. I very often Option-click the volume button, which lets you select input and output devices without opening the sound preferences pane.

I don't get why Apple just doesn't provide more UI tips, like tooltips on first use of the UI. There are so many little things like this that would be great to know. For example on Windows Dialog popups, the labels for each option underline the letter for the keyboard shortcut. Did you know that Apple has keyboard shortcuts for dialog popups too, if you press CMD+letter? It took me years to figure that one out.

It sounds like the purpose of muzzle is to enable Do Not Disturb automatically so you don't have to remember.

I have a few qualms with this app: [1]

1. For a Linux user, you can already build such a system yourself quite trivially by writing a shell script, compiling your own custom X server, and then monitoring the screen state for full-screen apps. For Windows or Mac, you just remote desktop to your Linux box with built-in software.

2. It doesn't actually reroute the notifications. Most people I know want to be able to perform presentations without the visual clutter of notifications, but they still carry a phone to check their Instagram while presenting. This does not solve their notification issue.

3. It does not seem very "viral" or income-generating. I know this is premature at this point, but without charging users for the service, is it reasonable to expect to make money off of this?

In reality, this is a great landing page and a cool idea for an app. Also, I have nothing but respect for people who share their honest, thoughtful assessments on HN. The future is tough to predict.

if you think compiling a custom X server is "trivial", we must have very different ideas about what that word means

It's a running joke about DropBox. The giveaway is in the link in the parent's post.

I think you missed the joke.

Does everything have to be a moneymaker? Like you said, this would be trivial to setup yourself. It's a nice piece of software that provides some advertising for his other products.

Go to the link in the comment...

Ah, I didn't realize that this was a reference to the Dropbox comment. Gotcha.

"...a week or so ago..."

That's awesome.

Seriously though. For those of us who need our chat on despite the frequent unpopular rants of our sister/brethren, I welcome this attempt to filter. Btw - excelent landing page!

Good tip, thanks.

The only reason I might like muzzle a bit more is that you don't have to remember to turn it on & off (according to the landing page, I have not yet tried it).
