On the main list view the user shall be able to perform very many varius actions on selection of entries like:

• tagging
• commenting
• reassigning to another responsible
• completing
• changing status, reporting time (?)
• changing iteration/release (very useful in planning)
• changing priority
• change/remve parent (?)
• combine into one

This would be useful for users that dont like such tools like this and log in to system only to update status really fast, others will love it :).

Very useful in iteration planning and reorganizing the tree.

Some actions shall be performed only on same type of entries (like assigning parent to task/bug), or only on one selected entry (like splitting the entry).

In the view it can be presented as checkbox in the first column, o on the left to the title.
