Clarify UI and/or add Advanced Help support

Hmm, I should consider adding Advanced Help support or something for those things, and some could use some language changes. Many of these are artifacts of the Fast Company version of this tool, which is why they are a little confusing. For now, I'll give you some quick answers.

Featured Content Queue page

1. What does the Reset button below the Topic and Feature Type popups do?

It resets all the filters. So if you've filtered by Type, by Topic, and even additionally a keyword, and then you press "Reset," you'll get the default version of that page, unfiltered and reverse chron.

2. Clicking "Slot All" doesn't seem to do anything.

This is a shortcut for slotting items, but it is mostly useful if you are using Topics. What it does is: if a node is tagged with a Topic, the slot all button will slot every item on that page in the queue for its Topic. If you check the "Include Home in 'slot all' and '+' actions" box, all items will be slotted for the Home queue as well.

3. What does the small "+" links do - can't see any effect when clicking them.

Same thing as 'slot all' as described above, except for that specific node.

Slot Machine Schedule page

1. It's not obvious what the upper Reset button does - can't see anything change when pressing it.

It resets any changes you've made to what you had initially. Sort of a "return to defaults" sort of thing. So if you were to change some frequencies and check some boxes, and then click that, they will return to their initial values. Not something terribly useful, but something Fast Company wanted and I left in.

2. What is the Preview button for? I have two items in the queue but pressing the Preview button just shows me the same information but only for the currently live node.

It previews any manual changes you are making to the schedule. So, for example, if you check the remove box and then click Preview, you will see what your schedule will look like when the Remove goes through. Very useful for when you are removing several items at once, especially when rotation is enabled.
