Ah, that makes sense. The blocks are new to me, so they had me baffled- thank you!
Yes, the hovering bit I'm familiar with, but I'm not always certain what the description that pops up is trying to tell me. I'll explore the section you mentioned and if I'm still lost, I'll assemble a list of questions so I don't keep bugging everyone. I'd rather discuss more interesting things than "what does that button do?" and I'm sure everyone else would to, although everyone has been very nice. Quite a change from my last experience!
Thanks again, Recusant!
