Multiple columns - Yes ContentFlow supports multiple flows (which can be columns), we frequently use 2 column layouts (for example this page is using 2 flows: https://www.brintons.net/about). You can also insert a snippet that itself introduces one or more flows, so it's possible to say insert a snippet which you can configure to show say 1 to 3 columns.
Move snippets between flows - No at the moment this behaviour isn't supported. It's on the idea board and we've been looking at it internally. There are a number of challenges that make it more complex for us than it might at first appear, in particular we have a set of rules in Manhattan that define what snippet types can be inserted into what content flow and so any move needs to be confirmed either server-side or ideally client-side (where currently the rules are not defined, though we have a list of the snippet types so shouldn't be too hard thinking about it...).
However these problems are really just internal to us and Manhattan, moving a snippet to another flow should be a relatively simple task to implement in JS, I'm certain we'll support it moving forward or would be happy to accept pull requests for this functionality.
