I woul like to see a very fast, simple, lightweight editor, a la kedit, in kde4. Usuallly kate is way more than I need.
Have you tried Kwrite?
BTW, I tried out one of the early versions of kde4 and found it to be buggy, incomplete and unusable, so I was pleasantly surprised when I upgraded to kde4.3; after using it (me, my wife and two kids) for a couple of weeks, we have wiped kde3.5.10 off the machine.
Thank you for your work on kde4.
It's not my work, it is the work of Aaron and hundreds of other coders. I just try to bridge the gap between coders and users. If you google Aaron Seigo, though, I'm sure that he will appreciate the thanks.
