Custom Cloud Storage
It would be super beneficial to add external cloud services like Google Drive or iCloud to Picflow. By a few clicks existing Databases in external clouds could be turned into Picflow Galleries, preferable with a two-way connection. (Tags, Comments, Annotations,...) It'd have tremendous benefits for a workflow that requires a gallery view as well as a standard folder view in a file manager. In addition, existing plug-ins, automations and workflows for Google Drive would extend the power of Picflow. Example: Automatic Uploads to a Picflow Gallery when files are edited with automatic versioning, if that cloud service has support for that.
Downloads only for approved customers
As a photo press agency, I want my clients to be able to download files, but not just anyone. In short, I would like a customer to be able to log in to your site, after which he/she will be given the option to download while a visitor without a login does not have that. Of course it would also be nice if you could see from 1 overview who downloaded which photo and when.
As we become more and more hybrid shooters (photo & video) it would be great if we can add videos to the galleries.
Would love to see an iOS application for iPad and iPhone with ability to capture photos and comment/markup them
Pay to download (Stripe / Square) integration
For clients who order images and needs to pay for the images prior to download, allowing the client to preview the images prior to payment but must make payment to download the media. I guess this would also need to some type of simple CRM for client info and to incorporate a simple method to compose an email via Picflow that would handle the delivery notification with a link to the gallery.
