Interested in this set, but there are a few nitpicks that would really bother me.
1) The 1.25x mods are super/hyper/meta, but the 1.5x mods are ctrl/alt/win. I think we should pick one or the other, or include both options for both packs (standard mods and adaptor pack). This would extend to the JD40 and Planck boards, which also use ctrl/alt/win currently. Not sure if this is partially a limitation of what tooling SP has available, but it would be nice to at least extend the ctrl/alt/win option to the 1.25x users. Currently, my best option for getting those mods is buying two JD40 sets. If you do decide to add the ctrl/alt/win to the mods pack, it would also be great for 60% users if you could add a function key as well.
2) Your numpad enter is symbol only, and your ANSI enter is text only (and like my first point, the ANSI boards say 'return' while other layouts say 'enter').
I like it, it feels well-designed, but it doesn't feel 100% cohesive, and it's the kind of stuff that would bother me were I to buy a set.
Even if you were to make the changes, I couldn't commit 100%, as I really need to watch my wallet right now, just want to put it forward for consideration. I also want to hear prices, as it looks like you're going to need to cut several new legends for the planetary pack.
