Allow users to search all text in a stored document, especially in a PDF file, returning file and page number where found.

Allow the use of sub-categories

Allow single sign on for my users.

Authentication of users via Active Directory/LDAP

Users should be allowed to subscribe to documents or categories and receive immediate or daily summary notifications of changes made to docs or category contents. That way they know what to read or what actions to take.

Inheritance of permissions from the containing folder/category, so that permissions don't have to be explicitly defined for every document.

The ability to add documents attached to emails into ODM. ODM would check a POP mailbox about once a minute to see if any new docs had been submitted. These would then need to be reviewed/authorized. Authorized documents would be added to a category/folder called "unclassified" with guests having read/write access. The admin would be able to rename the file, add description/comments before authorizing.

Need ability to have nested directories/folders to better organize 1000's of documents

Allow the edit/add user form to use a multi-select list for Department. This would allow users to inherit permissions for files for more than their single department.

Implement and off-site backup system to allow administrators to send their files and database info to an off-site backup server.

add an anonymous feature to allow for anon viewing of files.

User-defined fields are excluded from the default "all" search type. It is not a true "all" search without them - and often, UDFs are far more important than the ones included by default. Please enable this feature.

For example add file category field and remove date modified, file size. description etc...

I want some user only view document, not alow upload (add new document)

Add more date info to files:

* What is the date of the document was written
* What is the date of expiry of the document (contracts, leases, etc)
* Date fields should allow for year only, month & year only or full year, month and date. Sometimes not all parts of a date are known or relevant
Using dates of this nature allow users to search for documents that are within a specified age, or older than x for archiving or other purposes

It is good that we can choose to browse using a list that includes both Categories and User Defined Fields (UDFs). It would be great if we could browse by selecting multiple search criteria. For example a Category and a UDF... and another UDF... and another up to the number of UDFs that have been added. This would really help in finding documents.

API to allow integration into 3rd party business management application

After finding a document, allow quick sharing (via e-mail), with the document's direct download path included in the e-mails body.
This allows for example a technical support guy to send a programming manual quickly to a client, with a one button click after finding it.

Add a tag feature to files, similar to WP taxonomies or woothemes forum. Make sure it auto-completes.

Store files with their true file name. In case of clashes, add postfix. Make sure this feature is worked on at the same time as the "file renaming" feature.
