Get original image dimensions from block API

In 'Explore' mode, auto-expand channels that contain a large numbers of blocks so that browsing returns more than boxed categories and remains visual

Automatically enlarge info area if text is long or an image is added. Add image to info area of channel.

With the ever increasing number of are.na users there seems to be the risk of people abusing the 'open channel' system by mass-adding their block (MakeCashFast.com or nefarious sites to that effect) to any chanel they can click on, with very little to stop them. This prompts the question of 'chanel vandalism' and tools for users to report the vandals/blocks. I'd like to point you to this block: https://www.are.na/block/2063291 for a current example of this. I've seen this a couple of times regarding either my own channels, or channels with large amounts of followers. Cheers!

Sub-channels within channels. Example: I want to invite collaborators to a private channel, but there's 40 items I want to share. All items for the collaborator, but certain items are matched with one another and not all other items. TL;DR sub-folders for channels.

This also prevents me from having to create a separate private channel. Some kind of visual folder hierarchy or structure would be helpful as well.

Searching for users with the @ function doesn't work; when adding a space after @firstname, the lastname isn't a field that populates in user search.
