More things for the IDE (Integrated Development Environment). Xcode is the one I use for iPhone development, so hint, hint Apple.
Like a desktop program or web page allows you to hover the mouse pointer over something to get information about it, the IDE should give me more information about a variable when I make a gesture for it.
Now Xcode already has some hover information for some things. It shows the type and some contents of a variable.
What I’m talking about is giving developers the ability to see information they have set about a variable.
It would also be great to have quick access to documentation, known bugs, easy mistakes to make, valid value ranges, etc.
It would be better than having to track down the definition somewhere in the header files or source files to see if (maybe) someone put a comment by it.
It might also encourage developers to write more and better comments.
