Hi All,
I am considering the purchase of Responsive Site Designer but have not downloaded the Trial yet. Thus far I have read a bit in this helpful forum and a few of the Help-documents provided. Here's a few questions which came up. Thanks for all comments!

Design-updates:
I have seen a few video tutorials but I didn't gain a proper understanding on dealing with somewhat larger projects yet.
Say I've created a template with one section called WORK to showcase a dozen or more projects with text and image sliders in the same overall layout. How are global design changes (fonts, breakpoint-changes repeating elements etc.) handled in this case? Does one edit something comparable to a master-page in page layout programs or would one change classes or components one by one? How are local overrides (on page level) handled?

Dual language websites:
Is there an elegant way to create dual language websites with RSD or does one effectively build two separate websites
which later get wired together? I would like Design-changes to affect all pages in every language version – is that possible?

Menus:
Looking at the template section I don't discover a design (yet) which comes with a Menu-appearance which has become ubiquitous these days. A sticky (non scrolling away) Top-Menu on Desktop and a Hamburger which triggers a display filling mobile Menu. I see that 2.5 offers a Hamburger Style menu component – is its appearance easily customizable?

Image Slider:
I see that Coffeecup has a separate product called Responsive Content Slider. Are all its features built into RSD as well?
Inside the samples section I did not find an image slider which supports swipe events. Is that just by chance or is browsing through fullscreen images via swiping indeed unsupported?

Is RSD generally understood as the flagship program which combines features of the specialized applications? Does RSD therefore also have the Newsletter capabilities of Responsive Email Designer? If not: Is there a feature comparison chart of all Coffeecup software?

Blog:
My guess is that there's no inbuilt means for blogging in the Wordpress sense. But likely it's possible to create pages, which look similar to database driven Blog pages with RSD. I have also seen "Stream"mentioned but don't know about the present status of that tool. Did anyone build a Blog with RSD and also implemented commenting? Not talking about hosted 3rd party services as Disqus here but a comment-engine which is under full user control.

SEO:
I see that CoffeeCup offers two standalone tools for SEO. I wonder if there's inbuilt SEO optimization tools as well? Stuff like indicators that Meta-Descriptions aren't set, duplicate warnings and flags for thin content...

I'm happy for all input! Hoja
