@jaipster , the q2a development is not stopped . Rather it is bit slow than the user expects . There are too less contributors . @Scott works here in his free time and the creator of this software is busy on different project . And Now I am trying to contribute something what I can in my free time .
The q2a is already matured and works much better than other software available . Can be extended via plugin and themes . So the features you suggested is not suitable for core , should be in a plugin .
If you think it is slow , why dont you help in testing the new bugfixes and enhancements .
