I recommend studying the Chinese program - it allows you to do everything:
- splitting single units
- instant exchange of artifacts and troops
- autosave
- video recording.
All these add-ons like Laiter and the Chinese program are somewhat reminiscent of attempts to tune Lada cars. That is, yes, you can install a spoiler, a more powerful engine, two exhaust pipes, a heated steering wheel, but it will still remain a tuned Zhiguli.
And for the next step in development, a different conceptual platform is needed. For Heroes, such a platform became WoG, which makes it easy to do things that are difficult to implement with external programs or by editing the executable. Moreover, judging by the discussions on DF2, the development of this platform for possible future tasks is still ongoing there.
Having such tools, one can aim for very serious things in terms of interface (not to mention gameplay). Therefore, all new ideas will either originate from TE(WT) or will be quickly implemented there.
And external programs for SoD will at best copy some features, and with a delay and not necessarily with quality.
Pay attention - in all the foreign communities that you praise so much, there is a tendency to modify SoD at the physical level - somewhere they edit text files, somewhere they even write external programs. Because they acknowledge the imperfection of SoD. And only HeroesWorld with HP takes the so-called "conservative" position, roughly like the English in football up until the 90s. I think it's not necessary to clarify what such an approach leads to ...
