E.Z.Chooser - A simple MIDI Track output routing and sub-routing M4L device. Feel free to use, please help to update or improve!

This is a track output routing and sub-routing chooser M4L device i have designed using regular max and LOM objects. No java-script or anything else. The attached device is optimized for setting MIDI-Track output, but it can be easily modified to set Audio-Track output instead. I suppose it could be modified to set inputs instead of outputs as well. My main concern though is that some of the LOM track properties i am using, have been deprecated since Live 9.7, meaning that it may break functionality in future Live or Max updates. Currently it is working as expected, apart from a couple of minor issues which are listed in the "issues" sub-patcher, included in the attached device.
If anyone can help me replace the deprecated commands with the new ones it would be great. I hope also that by doing this, it may be possible to fix some of the issues caused by bugs present in the old commands.

Why use this instead of the M4L.chooser.js?
There were 3 reasons i was not happy with the M4L.chooser.js (apart from my inability to modify it due to my complete lack of java-script knowledge):
1. It has some bugs, for example it doesn't update the live.menu when a track is re-named. (This bug has been fixed in E.Z.Chooser)
2. It does not have an option to select sub_routings. (This option is included in E.Z.Chooser)
The third reason was an incorrect assumption i had made that M4L.chooser was inducing latency when changing track routings, due to the use of java-script. It turns out this is a problem of Live itself when there are many tracks present in a set, thus the latency is present whether you change routings from M4L.chooser, or E.Z.Chooser, or Live's track output chooser itself.
