There are a couple of problems with the new formatting bar:

1) The icon to turn it on/off doesn't make sense. It's a toolbar, and the "Aa" doesn't get that concept across. It's in a strange place, next to "@" and ":-)", icons that cause an element to come up over the text field without changing it. A lot of smart folks aren't figuring this out (and let's face it, no one reads the fricken' manual.) Don't believe me, check out the replies to this tweet:

2) Once you have the epiphany to turn it off, it doesn't turn off the functionality. I've been using Markdown since it was just a glint in John Gruber's eye, and it's actually easier for me to _read_ text *like this* even when it contains `code`.

If I opt out of the formatting bar, it feels like I should be opting out the fancy completion stuff, too.

In the next version of iPulse, I'd like to show GPU statistics. Unfortunately, the format
for these statistics is vendor specfic (see the "Performance Statistics" dictionary below.)

In order to cover as many devices as possible, I'd like you to run the following commands
from your Terminal:

$ sysctl hw.model
$ ioreg -r -d 1 -w 0 -c "IOAccelerator"

You can help me read the results by putting them in a code block (triple backticks).
