I think this is a KiCad forum . . .
You are right, i’m sorry
Upon Schematic re-organization i stumbled upon the available space in a single Schematic sheet, i cannot find the Place > Add Sheet button, is it normal?
Either . . .
Or . . .
Or . . .

Ah, my screen shots were from V8.0.9 
How excactly is this about Kicad?
Come on Mods
Sorry,
what is not about KiCad here? I’m asking for help on how to clean a schematic using KiCad and how to add more sheets to my KiCad project.
I don’t think there is a problem here, also i hope this thread will be useful to other people, maybe they will learn from here how to make better use of KiCad like i’m doing thanks to the kind people answering me here, don’t you think?
Just sharing free and open source knowledge and information here, isn’t it the main purpose of a public forum?
Already pointed out . . .
Your original post was asking for a general design review with no kicad-specific questions.
It is easier to say what was KiCad related. The only was: “How to add Sheet?”.
KiCad related = I_know_what_I want && I_don’t_know_how_to_do_it_with_KiCad.

There have been a number of Kicad specific details given to help:
There have also been a number of non Kicad schematic drawing suggestions given as well as off topic IC comments.
I’d give this topic a pass, as the OP is not asking for design suggestions only about the actual schematic drawing.
Compare to the below, a little down the forum page, which has nothing to do with Kicad:
Designed a power converter circuit. Wanted to see if I missed anything?
Just use buses and hierarhical sheets. You can even write block diagrams and parts of documentation directly in KiCad sheets.
IMHO LM2596 is still “popular” between DIY and small projects because of Chinese made gazillion LM2596 clones who are sold for pennies alone or inside DIY oriented DC conversion modules. There are a lot of newer Buck DC-DC converters now - smaller and more efficient. Also ultra low drop LDOs.
Not for nothing, but you might want to check this out:
Similar to what you are trying to do – schematic layout is OK but does seem to have a better buck converter topology; not sure that will work for you though (12v vs 24v).

I had also shared my first hardware project on the KiCad forum, and some of the feedback was a bit harsh… I was just getting started and didn’t know all the rules.
Later, I posted it on https://www.eevblog.com/forum/projects/ , and that really made a difference: the community was very welcoming and experienced, and the feedback helped me improve a lot.
If you’re just starting out, I REALLY recommend giving Eevblog a try.
There are definitely kind and helpful users on the KiCad forum too, but some can be quite selective😂

Yeah, we select to help with KiCad specific questions because this forum is dedicated to that.

Yeah okay I think you have pointed that out. That’s why I gave him my advice of changing forum 
We are not trying to duplicate EEVblog. In point of fact, we are working hard to prevent that and staying focused on making Kicad better. Sometimes it seems a bit arbitrary but we have quite a few people with enough forum permissions that we ‘mainly’ have a consensus. Whatever that is at the moment…
