This is inspired by Railware. I nice Feature to have would be an option under the tool section that could help with programin the dip switches on MM and other decoders. You simply put the addres in and it gives you the dip switch combination and the other way around. It could be used for example for Märklin c80/c81/c90 loco decoders, k83/k84 decoders and the CU keayboard and switchboards and possibly other system using simular programing. There is an example image from Railware:
Here is an k84 manual with a programming table, Märklin keyboard programming on page 8. There also should be some Selectrix dip switch decoders and Märklin Delta decoders
