Hi @TW_Tones,
many thanks for your valuable idea and comments! For sure I saved your comments in my Todolist of project to look at them later and see how I can I benefit from them and improve Gatha!
In the original post I have given links I past them here: [2] Gatha (Zoroaster) - Wikipedia. Also see original post here [1]. Proof of Concept: Gatha a Plugin Maker and Content Manager - Plugins - Talk TW (tiddlywiki.org)
It is an old Persian word refers to a section, part, originally Avestan hymns. I used it here to mean a collection of tiddlers for a special purpose like a course note, …
They are used for plugin tiddler and you edit them through a form! So not good to have two boxes at the same time! but one can directly create the fields
This is up to author! You can have a very long tiddler
It is highly recommended! Relink is an essential tools in all my works!
Yes, I tried to keep the UI simple, but these tools can be added
This is in my todolist! @telmiger suggested to be able to edit and hack or customize plugins! I will add this features into next releases!
Absolutely!
I think Gatha brings the knowledge of making plugins to the access of non-technical people! I think data/content
plugins shall be easy enough to be built by any ordinary user!
So, Gatha is the step toward this objective!
Gatha is very simple, but can be simpler 
Tinka has this feature! I think it is not hard to do that! I prefer to let me assign the version manually!
