geanynumberedbookmarks won't navigate me between files. It only works within a single file.
Is it intended that it be able to move the cursor to different files?
Regular Geany bookmarks only work within the current file.
I don't think it is meant to work between files, its not explicit, but the [doc](https://plugins.geany.org/geanynumberedbookmarks.html) for the plugin talks about saving bookmarks and other settings "per-file".
You could check the source of the plugin.
