lanux, A43 looks good. Do you know if it's possible to have it such that when a .txt file is selected, it is automatically shown in the 'Text editor' as opposed to having to drag and drop it there?
Also, the program's homepage says that dual panes are possible in A43, but I can't see how.
Everyone else, thanks v. much for your replies. I'll be evaluating DO soon.
I installed TC but immediately deleted it as it was v. ugly.
