I think I already mentioned that I’m quite fond of minimalistic UI’s and texteditors with an undisturbing interface.
Recently I stumbled upon FocusWriter (http://gottcode.org/focuswriter/), which is now by far my favorite app for writing. It’s awesome how nice it is to work with such a tool which eleminates all distraction.
I only wish all KDE applications would have such a mode, where fullscreen really means fullscreen. Imagine how awesome this would be in KMail or even better, KDevelop. Especially KDevelop is, while an awesome IDE, just way to cluttered so far. Maybe the Kate devs eventually get around to implement a real fullscreen mode =)
Until then I’ll stick to copy paste from FocusWriter, or to what I created for Zanshin.
