Re: verilog editor windows
Perhaps you could try a new Jedit? 4.4.2 does Verilog syntax highlighting window splitting code segment folding, indentation...
If you're not using an outdated version try Utilities->Global Options->Editing dialog or for a trying it out Utilities->Buffer Options. I found all that stuff turned off by default. In Global Options you select the language file editing options with Change settings for mode: verilog, un-tick Use default settings, select your folding modes etc.
