Railroad Plugin Suggestion for improvement

Hello Community,

I installed the Railroad Plugin and it is very useful for me.
Looking to the Plugin Information is there only the information available that it is

based on a library by Tab Atkins, and has been extended to make it more flexible

Here my question.
In case of any ideas to improve the plugin how to make such a proposal?
My ideas are:

  1. Possibility to make a railroad diagram not only horizontal orientated also vertically
  2. Possibilty to add a line feed
    in a box to have multi line texts in one box

Thx for your support
Stefan
