Version: 0.2.1 (using 4.2.1 (KDE 4.2.1), Kubuntu packages) Compiler: cc OS: Linux (i686) release 2.6.27-11-generic Some values are shown in pink and some in black and there is no way to change this. The cursor is also a blinking pink blob which means while the cursor is shown it is impossible to read the value (as the text and background are both pink).
The highlighting is currently hardcoded, using system colors of the current color theme. On the TODO list. But the cursor using the text color and filling the whole width in overwrite mode, this is not going to change, pardon me. It's working the same as you have with most text editors, please compare.
