Testset that contains several existing testsets
what do you think?

add the ability to enter all kinds of text effects and fonts and links etc....

When exporting a view, especially one of issues. The ability to sort by a particular column does not exist. This feature would give stakeholders the ability to generate reports. For example, export all open bugs sorted by priority.

When test status is changed from "Draft" to "To Repair" or "Obsolete" a comment should be attached explaining for the reason.

Currently, by cloning a test, the
Author is copied from the original test.
This may cause confusion when users clone tests and modify them.
Setting the cloner as the Cloned Tests' Author will solve this issue.

The option selected in the drop down controlling the number of issues displayed per page is not persisted. If you change the option, view an issue, then return to the "Issues" tab, it is reset to 20 issues per page.

It would be a great benefit to us if the filter coould be like it is in excel where you have the poosibility to customize it so you can define your own filter. For instance fileter on several "status", not only one.

It would be good if the table cell or text for the requirement status is colour coded to make it easy to identify requirements which are not covered, not ran etc.

When adding an attachment that is an image, display a small thumbnail of the image.

Add ability to create test sets straight from the test library using the mufti selection check boxes

Add Test directly from a Requirement and link them for traceability at the same time. When we create our tests they are based on the content of particular requirements so it would provide a much faster way to develop test coverage and prevent from have to search to associate them together afterwards.

Add ability to convert a search to a filter (which can be later customized).

enable an advance search, where we can set each field, whether it's a custom field or a system field.

once you have a test set deriving from the main test, i need the ability to add an attachment to the test set.
you can add one to the main test but that won't help.

For custom field use, add more field formats such as:
* time (hh:mm)
* External Link (URL)
* Multiple hierarchy levels in a linked list and not just one parent-child (also grandchildren etc)
*link other data types to a parent list
(eg: if you select A from parent list then a text field appears instead of only a child list)

...It will be very useful and will save time
