*Debian Buster *Geany-plugins v1.37 *Geany (git) built with GTK 3 enabled
The [spellcheck doc](https://github.com/geany/geany-plugins/blob/master/spellcheck/README) lists "GTK >= 2.8.0" as a requirement, but I think it should list it as "GTK >= 2.8.0 or GTK 3" because Geany itself can be built with GTK 3 enabled, and if it is, wouldn't GTK 3 be a req for the spellcheck plugin?
