Scope contains 20 source files and 22 headers. Using static is not an 
option, and marking everything global as hidden will be cumbersome, 
ugly, and easy to miss (inexperienced plugin developers are sure to miss 
symbols).

The only practical option seems to be compiling with hidden visibility, 
and geany_load_module() should be pre-defined as exported.

Please make this gboolean. A plugin may have the correct API and ABI, 
but be unable to startup / initialize for some reason. For example, 
Scope requires scope.glade in the plugin data directory).
