Well thus far the program itself works fine, although I havent tested its more fancy features like php parsing and FTP upload gadget. I will try those later on.
It is clear that some of the minor details have not yet been completed, but these are only cosmetic right now.
The text highlighting works well in the multi-syntax mode as well as the selectable pure modes (php only, css only, html only etc..)
At first impression the environment does look somewhat cluttered and busy. But I guess if you use it enough, you will learn to appreciate the nearby tools surrounding the work window.
The 'workspace' navigator side panel did pick up the variables used although it missed a few functions.
I think it might be better if the variables expanded menu perhaps did its checking occasionally in the background as a seperate thread from the front-end so it doesnt pause as it scans the file for the variables to list them for you. Just a minor frustration, nothing important.
Lastly i'd like to mention about the ability to collapse portions of the document much like in C++ IDE's. In many modern multi-language editors, beside the line-number column there is a small + box where you can expand and collapse portions of the document like functions or comments. I have grown to greatly appreciate this feature from editors like Quanta Plus:

If you were to put in this feature it would make this editor a far more viable choice for those willing to pay for such software (depending on price of course).
A feature I do like though, is the formatting feature. Very nice.
Great for me as i have a habbit of just typing down the screen with no regard for fromatting what so ever, other than what the editor inforces (function indent etc.). I know what it does and how it does it, why bother ?
As this program is intended to be a complete evironment (noted from the addition of FTP features and using local php for parsing), I would suggest incorporating the common features found in free IDE's like Quanta plus and others to stand a chance of making money with it as these features can obviously be gotten for free elsewhere.
I will continue to use this editor for a week or so and test out the php parsing and FTP features.
Please do contact me if you release further developments of this program, I am curious to see its development.

If you keep it commercial then I can guarantee you that you will need a lot to break through the other already popular commercial AND open source editors in order to get your name out there, but going open source can really turn some heads if you ever decide to go that way.

If you commercialize your product, then it'll just be another product that most probably won't even check out since it is not well known.
