Just to clarify Question 1:
Apparently there are sliders. I don’t know what a slider is. If there was some way I could see a printout of the screen with the words Slider over the top of the slider, that would be helpful. Then I could see where the slider is on the page.
And, if there was a print out that showed me what a 3 column layout would look like, that would be great – somebody may say that there is a preview of what it will look like when you change the option in the customiser…. that’s great, however it takes 30 seconds for the preview to refresh and I don’t want to take 2-4 minutes just to get an idea of what something is going to look like.
