I see it a bit differently, because a project has to start first. I have the same with my Imagemagick GUI and Ghostscript GUI. First you build in everything you know about the possibilities and over the years the program is then constantly expanded/improved. Not everyone knows everything and I’d rather build in fewer functions sensibly than integrate everything half-heartedly.
Every project also becomes much more interesting as soon as others get involved. Could learn a lot when dealing with ImageMagick. Unfortunately, that didn’t work with the GhostScript GUI. That’s how it is sometimes. One project is expanded, another freezes. But then it is still a GUI of the respective command
