As the final feature to list I also want to mention that I would be a fan of *SubWordCompletion*. (This used to be a feature of Xcode, but they removed it, unfortunately). With SubWordCompletion I mean that it can also complete on *parts* of completion terms, without leaving the completion modus, with the possibility to narrow down on the completion term fast. An example:

You're looking for NSNumberFormatterRoundDown.

Then typing `NSNum ⇥ F ⇥ R ⇥ D ⇥` should be enough to make the complete NSNumberFormatterRoundDown.

This would the breakdown of the steps in the interface:

1. You type NSNum

It completes to NSNumber

2. type ⇥

It stays in completion mode, showing you all possible continuations of NSNumber...  (Hit ⇥ again or hit enter to exit completion mode and use NSNumber)

3. type F

it completes to NSNumberFormatter

4. type ⇥

you see NSNumberFormatter... and still stays in completion mode

5. type R

it completes to NSNumberFormatterRound

6. type ⇥

you see the 9 possible endings of NSNumberFormatterRound...

7. type D

it completes to NSNumberFormatterRoundDown

8. type ⇥

presto!

I recognize that most of these features will not be simple to implement, but please forgive me for being an idealist instead of a pragmatist.

Best,
