Create a litte iPhone application that lets users insert/see issue, see task.

- automatic creation of folder (Alfresco)/task
- authentication

- query progress of projects and tasks
- log work time

CalDav Support to TwProject to permit bidirecional write access from external clients (ThunderBird, Outlook, Zimbra, etc)

Currently the timesheet can show the agenda, which is nice, but...
... wouldn't it be basic to have at least your planned tasks for that day shown, highlighted, or even prefilled?

StatusNet (formerly laconi.ca) is an OpenSource MicroBlogging Plattform. It uses the Twitter-API. It would be nice that the TwitterURL is customizable to support this one.
BTW: Identi.ca is using StatusNet

Current LDAP integration is horrifying and does not allow for proper search paramaters. For instance, if I close an account on the LDAP server, they can still login to Teamwork because there is no way to properly set a search filter for LOGIN. I can set the search filter for adding/importing users, but not for login.

add the same/some properties that documents of tasks have, to the documents of storage part so they have the metadata information and can be versionable...etc

Add the capability to use Google Apps as the repository for files.

Users and Project Managers should be able to view overtime hours in the timesheet.

TwProject shall be able to count the business days per month/week and check how many extra hours were made. Something like the "Missing worklog".

Overtime = Sum_of_my_working_hours - ( Sum_of_monthly_working_hours - my_absences_hours)

It would be nice to have the same feature as for svn repos.

A wider solution would be to support rss feeds, then there would be no need for other systems which can create rss feeds (e.g. trac).

Currently, the only option for attaching a file to an issue is by upload to the repository. This should be implemented like it is for documents tab on tasks, allowing the choice of sources/types and including the ability to attach a file from file storage.

We would appreciate the posibility to plan weekly not daily.
By seting plan/week instead of plan/day would make it easier for businesses with many short projects.

it would be nice if teamworks provide a way to sort the documents within a project by code, name, version, date etc ...

For example, the Project Tree page allows you to edit task status, but it doesn't prompt for a reason for the status change. Working with inline editable pages like this is very productive, but a pain if you lose information as a result.
