geanynumberedbookmarks doesn't move me between files

[uvtc]

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 for the plugin talks about saving bookmarks and other settings "per-file".

You could check the source of the plugin.
