Adding more info

Name: KompoZer

KompoZer is a discontinued open source WYSIWYG HTML editor based on the Nvu.[8] KompoZer was forked as a community-driven project with development coordinated through SourceForge.

KompoZer’s WYSIWYG editing capabilities are one of the main attractions of the software. In addition, KompoZer allows direct code editing as well as a split code-graphic view.

The most recent version is KompoZer 0.8 beta 3, released February 2010, using Gecko 1.8.1. The stable version was 0.7.10, released in August 2007. The only regular developer said in June 2011 that development “is stalled at the moment”.

I’m interested in this being on flathub, that is the point of flathub to rescue old stuff.
