Except the wishlist that some people had mentioned before:
http://forum.cakewalk.com/SONAR-X3-Wishlist-m2629986.aspx
And here is my wishlist to any coming versions of Sonar whatever the update x2b of x2 or just the x3, and some bugs need to be fixed too, it would be too hard to use without these added in:
1. Complete real clip blocks support inside each tracks, which really let us to create the empty clips.
2. A real individual audio wave editor window or view for each audio clips that come with the complete offline audio editing functions and tool bars, just like the one in Nuendo and Cubase.
3. A real individual midi keyboard lane window or view for each midi clips that come with the complete midi editing functions and tool bars, just like the one in Nuendo and Cubase.
4. The editable info bars whatever in the main project tracks window, audio editor window or midi keyboard lane window that always let us edit and fine tune the detail properties of every objects, just like the one in Nuendo and Cubase. (This is what WE ALWAYS NEED and NECESSARY, e.g. some times we have to fine tune and move some automation event points in to a very tiny free distance that too insensitive to be dragged by mouse)
5. a complete midi batch functions that let us to edit a selected group of midi objects in a very handy and easy way, e.g. legato function, automation events value batch increase, batch decrease, value compression and expansion, value limitation, value equalization, time length adjustment, etc....
6. The FX slots that provided in post fader position of each tracks and buses in the mixer, that allow us to place some special VST plug-ins after the main final fader of each tracks and buses, e.g. custom dithering.
7. A preview switch that allow us to switch between different bit depths on fly when realtime playback, but not for offline fast bouncing, to let us instant listen that how would be the sounds like after downmix bounced out, so we don't have to listen to the results from bounced audio file outside of Sonar everytime. This is very useful, because sometimes the sounds result could be heard very different between 24bit and 16bit, e.g. the release tails of the strings.
8. A complete support for VST 3 and ASIO 2.4, and for Windows 8.1 and multi touch operation interface support.
9. Control room buses.
10. Total audio input meters, total midi input meters and audio buffer time usage meters which separated from the tracks, just like the one in the Cubase/Nuendo transportation toolbar.
11. Let us to config all the windows/views are dockable or all flowing around in Sonar main window.
12. Full scroll bars support in "INSPECTOR" that let us scroll the full track/bus even in a small size 19" monitor.
13. Auto classify the synths and FXs of plugins by their functions, PLEASE, so we won't feel too chaotic and headachy to search any synths or FXs if we have installed any large plugin libraries just like Waves.
14. Please do not always auto shutdown and turn on the andio engine easily again, please be stable, and let us to config when would the audio engine auto shutdown and turn on again.
15. And also, gapless audio engine also please, and more stabler audio engine please.
16. Please fix plenty and plenty of bugs in Sonar X2/X2a, Until now I still can feel Sonar is really still buggy.
e.g. One time I had created 1 midi track and 1 audio track for piano arrangement, and 1 more midi track and several more audio tracks for string ens. When I had entered some midi notes into the piano midi lane, and copy the notes by several times in the same track, the notes are shown in one of the strings audio tracks in the different time location too! Yup! midi notes shown in a audio track!

Andalso when I recorded some midi notes into the string midi lane, I don't why it auto created another new midi track too and the same notes of the string midi track appeared in this strange created midi track in the different time location too.
Just a few little working step can make my whole Sonar project like a mess and a hell.

And there are so many bugs still in Sonar too, please fix them all too.
Any guys here get any other wishlist items and bug problems wanna share here?
