boolean inverter
Select a block of code, hit a keystroke or a button, and every true/false is inverted.

Inline Errors/Warnings/Exceptions
I would love to be able to hide my Problems view and simply see in-line problems. Sure, the Problems view would still be useful for tracking down problems in different files, but 95% of the time, this is what I want.

Unified Sidebar
I hate to keep loving on Xcode, but I’m a fan of their unified sidebar. Instead of Eclipse’s approach of making a different view for every possibility, Xcode, slaps them all in the sidebar, basically mimicking the functionality of most desktop mail clients. It’s much cleaner than Eclipse, and you don’t have to constantly bounce around between perspectives.
I realize the irony of a developer complaining about missing features in an open source project that has plugin functionality, but good god it’s hard to write plugins for Eclipse.
A designer friend of mine wanted a custom flash player built for the videos he has on his website. Given the complexity of his design, I opted for creating the UI nearly entirely in Degrafa rather than trying to skin standard components.

Just a small point – if you roll over the error or bug icon on the left of the line number you get a tooltip with the error description, not exactly what you propose, but better than looking in the Problems view.

@Robert Bak:
Right. I was never too fond of the mouse-hover, mainly because of the delay. I’m also fighting the lovely SDK-14794 bug right now which prevents the gutter lines, breakpoints, and warnings/errors from scrolling.
