Adeel, would it be much effort to implement loading custom libraries at startup? Just by specifying them e.g. in OMEdit-Settings.xml?  That would already help a lot.

I also copied "MyLib" to the Modelica folder and it works fine but that's definitely not the way to go since all references must be changed to Modelica.MyLib. Loading a lib should be quite easy anyway. OMEdit docs say that the MSL is loaded using loadModel(Modelica). Of course this works with any other package. And the parsing for the tree view should be just the same stuff as for the MSL... or am I completely wrong at this point?
