Hello Salbovia,

Thank you for your feedback. We really do appreciate it and want to make sure we gather as much of it as we can. 

"I prefer if galleries have a border, are we allowed to customize these in Special:CSS?"

At this time it's a little early to create or discuss CSS customizations, since we still need to process feedback, fix bugs and build the editor tool, all of which could result in changes to how the galleries are rendered on our end.
