First implementation of available does not have the multiselection. In order to set several items as av. offline at the time, would be interesting to have the option.

The main problem is the bottom bar: currently with 5 items, a sixth one will make the bar pretty crowded and the tap area small for each one.

Options:

• Check the bar with 6 options
• Make the bottom bar "swipable", so the user can slide it to get more options that are not visible at a glance (if feasible)
• Set as 4th or 5th item a three-dot-button that opens a card with the remaining options
• (your ideas...)

I would suggest to add a three dot button for the right item. For this item you can show a popover menu with more context items. If there is more space available, like on the iPad, we could show more items. Maybe it would make sense to add a new drag and drop view, if you drag an item to the toolbar, when fixing this issue.
