I like the idea of LC+2.0 with SensorTrack capabilities. I was disappointed that the sensor wasn't added. It would have been a simple thing to include since LC+2.0 is just TMCC with Bluetooth included. Some updates to the Legacy system would be great. Legacy is amazing, by the way. I use it on my layout, and I love it.
By the way, I love the idea of Wi-Fi built into the Legacy Base. Bluetooth could be great, too. Then operators could run their whole layouts with one truly universal system. The updated Legacy system could run any LC, LC+, or TMCC/Legacy loco, and conventional locos with Legacy Powermasters.
Some more ideas:
-Dynamic brake lever plus sounds in locos so equipped (something I don't think we have in O-Gauge)
-Dialog buttons like the I-Cab App on the phone so operators could access their locos' dialog easier; plus, new, better dialog is a must.
-Legacy and DCS full compatibility (operators could run MTH DCS locos w/ Legacy; DCS will hook up to Legacy already and run Legacy/TMCC locos)
-Operating Tracks/Uncoupling Tracks with built-in command-control
-More operating accessories
-Bring back the Prewar Lionel Tinplate Trains that MTH made, but this time, made by Lionel and include Legacy or TMCC and Bluetooth (and/or conventional versions as well) Lionel needs to get the tooling back from MTH.
-I've never used the DCS App, but I have watched You-Tube videos showing the basic operations. I think that the LCS App and I-Cab App should have a throttle arrangement similar to the DCS App with the plus and minus instead of the slider to increase speed. Then operators could get finer speed control, especially when running Legacy locos. The 200 speed steps on Legacy locos is amazing. I ran my BNSF GP35 at speed step one, and it just crawled. Wow! Very slow.
-Also, the LCS App on the I-Pad needs the quilling whistle and single shot bell.
