Hi Hardboy,
Over the years, I tried out several text editors, but I always came back to CygnusEd. By far, personally speaking, it's the best and fastest text editor on the Amiga, with enough options to keep me satisfied. Although programming is limited to hands-on, so if you don't know your code, don't expect it to help.
Unfortunately, I don't think it's being worked on anymore.
