Firstly, sorry this may not be the best place for discussion, MS Lists doesn't seem to have it's own Hub yet (Can an Admin please make one? =)
Lists has just launched for our tenant, and I've checked the road map for development, and really looking forward to the full features & interoperability. Currently we can't use the Content files field, am I right in assuming this field just isn't ready yet? I love the way Airtable allows you to "drop" images into a cell and they upload. I hope this same functionality will be considered.
I guess for now will just use the "Attachments" field... ¯\_(ツ)_/¯
.. also, where's the best place to request features please, I'd love to see "Excel/Airtable" style tabbing of lists/data, and ease of lookup between the data. Makes is so user friendly.
