Thanks for the constructive feedback.
First of all, the typo in the banner has been fixed.
The set actually has a rather odd kitting as I intended it to reflect a chaotic lighting atmosphere, with light sources placed more or less randomly, as in a megalopolis in the middle of the night. That said, I'm not closed to the idea of evolving this kit, and I'm even considering splitting the base kit and the novelties kit.
There's actually a translation error for the word "Bar" (I had put バール but the correct translation is バー; my bad). This will be updated on future renders.
I really like the idea of a novelty for F13, I must admit. I didn't think there would be many of you mentioning it! So I'm going to plan this

Regarding R4 PgUp and PgDn, it will depend on the final cost of the base kit.
Concerning the kitting, as mentioned above, I think it would be a good idea to make some changes. If I separate the novelties from the base kit, I think adding basic support for 40% layouts would be feasible. The (initial) reason behind this all-in-one kit was simply that I couldn't imagine this set without its novelties. They're an integral part of the idea behind this project (and also part of the objective of a more competitive price than that of a base kit to which you have to add a child kit as well). But I think I've come up with a few interesting solutions, which I'll present to you soon.
Thanks.
