I would suggest that that page is an excellent list of ideas that should be
considered before venturing further (I've been left far behind in some of the
discussions here i.e. on Namespacing).
As perhaps a more basic coder I like the ones that reduce the verbosity of the
code (and the 'problems' I have to cope with the most) and I feel these would be
most appreciated by new users. So IMVHO the ones I think should be considered for
adding first are (with some comments)..
 
  3. Assignment on declaration 
- I can't see any downside to this? It removes a potentially confusing
       difference between constants and other variables and more importantly saves
       typing!
  24. Named loops and blocks 
- I like the elegance of "exit i" but as discussed it won't work on while
       loops so I guess labels are the way to go and this would save all those extra
       flags you have to add.
  4. 'Next Interation' keyword
  5. 'Repeat Current Iteration' keyword
  7. Scope of a 'For' loop counter to extend beyond the loop.

  21. GOTO construct. 
- I have no great desire for this and don't (really don't!) want to start
       any new disputes but just a small suggestion.. GOTO is disliked as it could
       branch anywhere in the code and thus become difficult to follow. How about if it
       was only allowed within the scope of its own proc/func?
