The plugins are not necessarily written and maintained by the Geany crew. Plugins can be listed on plugins.geany.org so that Geany users can find them easily, but the author is not forced to set them up in
While I would agree with all of this it just seems sad that such a powerful feature (besides ultraedit and you guys, no one seems to have gotten this right) is left as a plugin and especially one which is not on the nightly built site. You really should consider making this part of the core geany app. I can't believe anyone would not want this functionality by default.
The solution is, as Frank said, to compile the extra plugins yourself.
Just copying the binary release from the 0.19 version worked for me.
