Reach your audience via SharePoint communication sites in Office 365

Feedback coming up Mark-Kashman:

• Will we / when will we get all new features in other Modern pages? I see the new WebParts, but where are Section layouts?
• Can we please improve keyboard-based scrolling in modern pages and these new "communication site modern pages"? When I open a communication site I CAN NOT scroll using Page Up/down or the arrow keys. I first have to click on the scroll bar, then I can use the keyboard - this sucks for keyboard based users as well as people with disabilities.
• Hero WebPart: Why is it called "layers"? Tiles is perfectly fine, but layers usually means layers on top of each other (think Photoshop, think Onion). I would say we are looking at "panels" here. Please rename before GA. It ain't layers.
• Choose a new section layout (e.g. One third right column). Place the Hero webpart in the smaller right column and try to edit options and you get "Can't show layout options. Make your window larger and try again." No matter how much I zoom out, I can't set any options.
• I was looking forward to the new Events webpart (what are we calling these SPFx-based things anyways? They do not show up with ?contents=1, so they are not really WebParts. Add-In Parts? App-Parts?)! I was very sad to see that it's just a simple view of a regular calendar list. I thought we would be getting a new kind of events list - why not improve the old calendar list? Responsive views?! Touch-based layout? Modern JavaScript framework things?
• Image gallery:
  • Let me choose how many images are displayed.
  • Let users use a Masonry layout (Tiles, but better) - masonry is all the rage and looks pretty on pages.
• What is the "Form Templates" document library for in all Communication sites? Since InfoPath is a dead horse I don't know why this is included in this new site template?

What else is new and only available in Communication Sites? I see the top navigation is a bit different and the navigation editing experience?
