I am a registered owner of RSD, and the new beta is great. I was wondering if Responsive Content Slider is going to have a Flex Box option and also the ability to zoom the workspace to see breakpoints under the right panel.

I feel this is really needed

Flexbox is hugely beneficial for responsive design so I am sure it will come to Responsive Content Slider as well. No ETA as of now though.

Zoom will very likely be included as well, just no ETA now

To clarify, we're a small team lucky enough to be able to make really cool apps. However, we have to tackle these updates one at a time and coming up with exact dates is difficult and will lead to disappointments. Now if everybody helps to grow our user base we maybe could expand the team a bit...
