Rant of the Day.
It's unbelievable that Apple locks such basic UI feature as controlling the default icon sizes on iPhone and iPads.
I have an ipad mini, and like it's portability, it travels with me when I won't take a laptop, it's on my bag when a larger screen than a cell phone comes handy.
Now got an iPad 4 with the 9.7" larger screen, and honestly, the icons look weird, too large on it.
"That's the way it is, that's the way it always has been. 4 by 5 " is what web search tells me.
Other than a nice tool, which requires Rooting (aka jailbreaking) the device. 😔
For the record, here is the tool I mentioned, it seems a nice and basic right of a user - I have always had that in Windows, which mac people like to demean. Smoke that, Apple.
