1) Does/will the "form preview" work for Mobile?
Not sure what you mean here. It should be the same as in 7.0
2) In previous version where we had a small section to write rule for "Availability/Applicability" and etc. Has this been improved to provide full size editor?
Yes
Secondly, any attributes used in this section was not detected by "Search" and "Error checking" before.
No changes from 7.0
3) Has there been improvement in creating and applying CSS visually in the system?
No
A few screen shots to showcase these will be appreciated.
