1. Per-project audio. Your comments are confusing about having to switch folders when starting a new song. And, what hoops are you talking about? You can see the associated clips for all tracks.
You get a nice formatted display window when you click on Project>Audio Files, containing track and clip information, for example for a quick project I set up, called Test-Proj-010, which has 3 audio tracks:
Project File Name: D:\Cakewalk Projects\Test-Proj-010\Test-Proj-010.cwp
Project Audio Folder: D:\Cakewalk Projects\Test-Proj-010\Audio
Global Audio Folder: D:\Cakewalk Projects\Audio Data
Total Project Size: 241.6 MB Min/Max Bit Depth: 24/24
(then you get info, formatted as: File Name \ Path \ Bit Depth \ File Size \ Status. Within File Name, you get: Project Name \ Track Name \ Clip Name - please note I am only showing the File Name info here)
Test-Proj-010, Vocal, Rec (06).wav
Test-Proj-010, Backing Vocal, Rec (10).wav
Test-Proj-010, Harmonica, Rec (08).wav
Test-Proj-010, Harmonica, Rec (14).wav
SO, I am not at all sure why the above is a struggle. In addition, I do not recall any wide-spread (or even occasional) complaining about folks using per-project audio. Actually, when it IS mentioned, people are RECOMMENDING that others use it, as it makes keeping track of tracks easier.
2. Screensets - some folks use them, and some folks do not. It is a personal choice.
3. Browser - it's a simple 'B' to toggle its display off/on. I never have to float it for any reason whatsoever, though I could. And, simply double-click on any inserted synth in the Browser to open its UI.
4. What YOU consider useless freebies/options may be highly valued by others.
There is NO doubt that Sonar 8.5.3 was and IS a great release. In MY opinion, it was one of the best ever releases of Sonar. That being said, it also required a gigantic knowledge of key combinations to accomplish a lot of tasks, and it was difficult for newcomers to become proficient at being productive.
What began with X1, with a complete redesign of the UI, was an incredible undertaking to improve the usability for a wider user base, along with added functionality. X3e is in many reviews, and in my opinion, even better than 8.5.3 - it is quite stable, and much easier for a much wider user base to use.
Yes, things are moved around, changed, deprecated, added, and all of that takes an investment of time to get a handle on, but in the end, X3e is a great release.
I wish you the best with it all, and will do my best at assisting you with any issues you run across.
I DO think you should consider that Sonar will never ever go back to the 'black arts' methodology of 8.5.3, but as noted in other posts above mine, DO fill out feature requests for things you would like to see. Some may make it into future releases.
