First HTML editor I worked with ever, was called "Little Web Thing" which was succeeded bij "Arachnophilia". This was on Windows, recently I noticed that the programmers of this excellent piece of software also uses Linux. They put a .jar file on their site which should work flawless. It opens as a zip file, and I really don't know how to install this, or how to make a .pisi of it.

Ok I did not read properly:
Those who downloaded the JAR file version:
Open a command console (Linux: shell console), move to the Arachnophilia program directory, type "java -jar Arachnophilia.jar"
For convenience, this command can be made part of a shell script, and those using X windows can easily make a desktop icon.
