Also the ability to privatise attachments. Each task, attachment, comment should have the option to allow to view by all on the project or select who can see them by users.

Hi Nathan,
Thanks for considering this feature, I much appreciate the effort that has been put into this software already.
In my opinion this feature would be in a "need" category for a lot of people and would be highly considered when deciding on what software to use.
While the other highly voted on features (undo etc) are in the "want/nice to have" category for the folks already using it.... Just my 2 cents.

Please consider my earlier suggestion that should be super easy to implement, as all the functionality is there already.
I imagine that it would only take the following steps:

1, Creating 4th type of user called "Contractor" or something similar
2, set "All people/Resources" filter parameter for "Contractor' to his/her user name
3, Hide "All people/Resources" drop down list from "Contractor' so they can't use/change this filter.

This might not be the perfect solution that fits all but would certainly allow project managers to get more people (users!!!) involved in using TeamGantt.
Please advise if this is feasible.
Thanks

Thanks for all the feedback on this. It is something we are considering, although I don't think we will be able to get to it as soon as we would like as we have a pretty good backlog of features going right now.

Hopefully we can work this in at some point next year. I can definitely see how this would be very useful.

Could be simply implemented by creating a forth type of user, beside Basic Advanced and Account holder?
This new user type could only see the task that are actually assigned to him/her (or resources), allocating a existing filter somehow to the login.

This would be very useful for using contractors.

Can someone from Teamgannt please advise if this feature is being considered for implementation?

I would like this as well. We work as teams, but some projects are sensitive and so we don't want EVERYONE who has access to the main project to see details of some of sub projects

I really liked the teamgantt. I would like to invite new users to view or edit the entire project or a specific group, subgroup or task. Do not wish they could view/edit the entire project.

This is a very important feature if you are allowing your client to see the project plan. Almost every other planning/collaboration tool that I have used/tried (yes - many of them) allows you to assign tasks to certain team members and keep them private.
