+## Future developments
+
+A bunch of random, probably useless, ideas:
+
+### A bookshelf
+
+✅DONE
+
+Because books matter more than model trains themselves.
+
+### Live assets KPI collection
+
+Realtime data usage is collected via a daemon connected over TCP to the EX-CommandStation and recorded for every asset with a DCC address.
+
+### Asset lifecycle
+
+Data is collected to compute the asset usage and then the wear level of its components (eg. the engine).
+
+### Required mainentance forecast
+
+Eventually data is used to "forecast" any required maintenance, like for example the replacement of carbon brushes, gear and motor oiling.
+
+### Asset export to JMRI
+
+Export assets (locomotives) into the JMRI format to be loaded in the JMRI
+roster.
