More toggle buttons in top row
You know, AI has a lot of options that can be turned on and off.
And some of them switched on and off quite often: snap to grid, guides, smart guides, edges, corner widgets, bounding box...
Of course, all of them can be accessed via View menu, but uou just don't see them there! Users need no only SWITCH them, but KNOW what current state is.
Are my guides are turned off or I've deleted them or moved occasionally?
I want to draw a complex thing — is my grid's snap is turned on or I need to do it before I start?
And so on.
So we need indicator switches.
You've started understanding it, when added these to Properties panel.
But you take them away from those who don't use this panel.
And yet you have a perfect place for these switches, in fact you already sort of using this place! It's right next to the rocket GPU icon.
Put grid-snaps-widgets-indicators there, so we can always know what our current useful limitations are.
