As people use more and more the hierarchical test organization using the Test Repositoryand the Test Plan Board, a new flattened view eases the visualization and selection of all the Tests underneath some folder, including its sub-folders.
While the default hierarchical view provides a way to see how Tests are organized, the new "Flat View" provides the means to obtain all Tests underneath some given folder, eventually filter them using some criteria, select a subset of those and then do operations with them, no matter in which folder they're stored in.
Continuing our previous and on-going work, we're doing some architectual changes that will provide benefits across several different areas in future versions. Some of this improvements have been addressed in previous v3.1.x releases and v3.2.0 adds some more, including the calculation of the Test Plans overall status/progress bar, global and per-folder (in the Board).
The work we've done so far will allow us to provide additional improvements on several areas, which we'll be doing gradually.
Improving performance is an on-going effort, so expect additional enhancements to come in future versions.
