In MLCad you have the Favorites under the parts tree.
You can drag the parts you like to use into that Favorites.
They will be stored in the registry in the folder
Computer\HKEY_CURRENT_USER\Software\Lachmann\MLCad\Favorites
For each part an item "Entry1", "Entry2" etc. is created with just the filename as string entry.
Also an item "NumEntries" with the number of part entries needs to be there.
So this can be an entry point for a solution from your side. Problem is still to determine the parts that should go into the Favorites.
