I was very happy because of the annoucement that SubEthaEdit will have a future! I was using it for a long time, since I bought my first Mac back in 2008 or so. It was a very good editor and did a good job for serveral years on my Mac systems. The last years the program was not maintained very good, but worked until the last releases made it kinda slower on newer Mac OS releases.
This times seem to be over
But good news! The developers aggreed to make the source code open source and one of them will work on the future of the project. That are wonderful news. Not because the program maybe will be free to use now. But the open source code base may allow some extensions and plugins to make it a competitive solution to the other popular editors out there.
