Delegate access from one user to another
This would be used in the case that, if for example, a user goes on long-term leave, and can delegate the access to another user who is the back-up on this role so that this person have the same access that the first user has (in all the groups that the first user has access to).
Provide file and folder level access list of all users
Provide a way to check which user has what level of access related to ALL files and folders in the account. You could offer this as a query from the database, so one could search on a user and the application would list the files /folders and the respective access levels.
Bulk delete or select attachments or files
It would be super convenient to allow bulk deleting, similar to how gmail lets you bulk process. Perhaps even a bulk download option too, especially since some files (like images) can't be previewed from the browser page directly.
Identify Members who are not logging in.
I would like a report or facility that I can easily see who has not logged in. Or on the members list to include the last logged in date so I can quickly identify the members that need to be encouraged to log in. This would be extremely useful when we launch a new product and I can see who has not accessed this information.
Add notes as attachments to tasks
At the moment you can add files and google docs as an attachment to tasks but no notes. I'm really missing that features as I plan to work a lot with notes.
Add tasks/notes via email
It would be great if clients could add both tasks and notes via email versus having to be logged into the portal. The portal for many is just one more place they need to go to 'work', which can be a deterrent for many. If they had a custom email address, like Asana or other PM tools, they could simply add the task via email and see updates.
Make annotations with a pen over images or documents
For me, this would be ideal for images. A lot of my work is graphic and a client can accept or request feedback of the images provided. If they have a pen tool, they can highlight over an image or document which section needs changes. This makes it easier for both parties, as sometimes clients can't articulate exactly which section they need changes for because they don't know the name. (i.e. the thing below the black bar on the left...)
Identify Shared with on Documents
You are able to share some documents with nobody, it would be good if you could tell this from the list. Maybe the padlock being a different colour to help identify them.
