I love PhpStorm! In fact, there's really only one thing that's been bothering me: that there's no automatic tooltip that gives you the documentation for certain function or member - the same information you get when you press CTRL-Q. Or am I overlooking it ?
Up till version 3.0.1 there was a work-around that I found sufficient: you could press CTRL-Q and dock this documentation window to for instance the right-hand side of the screen. When you 'selected' another function, the documentation window updated to reflect this. However, since v4.0.1 the documentation window no longer updates when you switch to another function - you have to press CTRL-Q again.
The ideal solution would be to add an option (I think it would fit nicely in the 'Editor' > 'Code Completion' settings page), where you can enable/disable this 'automatic tooltip' and specify the delay in ms, just like for the other 'code completion' settings.
Also, is it possible to again make the (docked) documentation window update to the current (function) selection ?
PS: I'm using the Windows version, maybe the other OS versions do have such a tooltip.
