I am using gedit quite a lot. It’s reasonably fast and it provides some nice functionality via plugins.
But I don’t like that gedit window stays open even when there are no tabs. I know that it’s a feature, and that there is a CTRL+Q for closing gedit, it’s just that I would like to use CTRL+W all the time.
Some time ago I patched gedit, but today I realized it’s better to write this as a plugin so I can use standard package from Ubuntu and not have to rebuilt it by myself.
So, here it is — gedit tabclose plugin, version 1.0. README and INSTALL files are in the archive.
