I love the potential of the scheduler to totally replace AcuityScheduling!
One missing thing for me is to display clearer indications of open slots.
At first glance I wasn't immediately clear that the white spots were open spots and wasn't sure what the gray spots were. Of course after a minute of looking at it, I guessed correctly and clicked on a white spot.
So it'd be great if the white spots can say "click here" or "open spot".
Or to have the gray (blocked off times) be darker, for higher contrast with the open spots.
Also -- it's not obvious that one can scroll down on the calendar to reveal times after 5pm. It'd be nice to have an arrow pointing down with words "scroll down for more available times".
