At the moment we have Read, Write, Write and Delete and Administer.
I think it would make sense to make "Write" really an only write access.
Add a new rigth named "read and write", which will be athe actual right "write".
And the "new" right "write" will really only enable to write to a folder/adressbook/task list.
Example: we want to send a task to a employee. So we want to be able to choose the employee while adding a task.
But we do not want, that everyone can read the whole task list of that employee.
So at the moment, if you want to be able to add a task to another task list, you must choose the right "write". But with that access right you can also "see" the complete task list.
To make it complete I would suggest to rename "Write and Delete" to "Read, Write and Delete".
Thanks for your support!
