The suggestion is quite interesting, but won't it happen that a Hero can get a SU (super ability) earlier than usual, around level 17-18?
Also, I want to draw your attention to this topic:
/topic/at/1125663/
The author worked on the mod for a long time, but couldn't implement it because he got confused with the variations

No, in the screenshot, he was just making captions =)
For all Factions, the central skill will be available at level 23 (by removing some of the faction's secondary skills as prerequisites for learning the center perk).

Regarding the branch you linked. Yes, I saw it; it’s very cool! I would also like to be able to move skills like that. Unfortunately, at the moment, all I can do is remove skill blockers (however, I don't want to break everything, so I haven't changed anything yet, but I have been thinking about doing something similar to what's shown in the screenshots).

I also encountered a problem: SkillVille doesn't recognize my changes. I looked into the mod to see what's going on... everything is coded using numbers, it's terrible =) I won't be able to figure out where and what to change. The only thing I think I can do to make my changes visible in the skill wheel is to add arrows in Photoshop indicating which skills are "required" to learn in order to progress to the center perk.

Added after 22 hours 34 minutes
I started with the Knight (so far, I've only done him).


And then a question arose... I removed the arrows in the skillwheel so that the Hero's actual progression would be displayed correctly on the wheel.

BUT! BUT!
The outdated icon (Experienced Warlord) is still highlighted.
YES, there is no arrow anymore, and intuitively it seems clear that if there is no arrow, then you don't need to learn "Experienced Warlord"...
But still, the highlighted icon is annoying and may mislead.

In short... I couldn't figure out how to highlight what displays accurate information and not highlight what shouldn't be highlighted. So, I wrote an explanation. Of course, this isn't exactly what I wanted. But at least it draws attention and explains that you should trust the arrows =)
