I'm contemplating specialist sheets, but to be honest I may just make it one really, really big sheet and make bookmarks (5 pages would probably be the tops). I've already added in an extra vehicle slot. Another thing I'm considering is having "Stuff Pages", essentially 1-page standalone things with copied over vehicle/augmentation/weapon/whatever slots, but it's at Priority D, so to speak, after creating a sheet that works for at least 75% of runners without any issue. Augmentations aren't as high issue as magic, because they do eat from Essence, and while it's possible to get a lot you probably won't have that many on a starter character, meaning they'll probably go on the end of page 3 or early page 4. As an added note, essence loss from cyberware can be calculated. I'll probably include at least 20 slots for cyberware, which should be plenty unless you're Delta'ing a lot of really small things, which could probably go in notes (like cybereye attachments in 3rd Edition, for instance). Again, in 2.2 there's already a third page with more spell and power/spirit spaces (if you follow the example for "Silver" from my site, you'll see that both I and Catalyst use the slots as such), a second vehicle (there will probably be a couple more on a later page as well).
In short, my goal is to take everything possible into a single 4-5 page sheet and make it flow well. Rather than go specialist, I'd rather just go really long so that people don't have to dig up a special character sheet for everyone; my idea is that you can have one sheet on a flash drive and copy it to all of your players, rather than need to send them a link.
I don't want to modify the built-in character sheet, which is the first-two pages; it comes through pretty bad so I'd have to strip off a lot of the stuff, then add it back in using the proper methods. Remember, I'm working with print material using a digital production pipeline; the two are not necessarily the same, and Catalyst used Adobe products (ID6 for the PDF) while I'm using entirely FOSS stuff. This means that while I get by for the impressive material price of $0, I can't necessarily do everything they did the way they did. You may notice that my fonts aren't actually the same ones as the character sheet had, just very similar ones, for instance. Unless someone wants to hand me what would probably amount to $120 or so for distro rights for their fonts, I'm sticking to what I've got in my library, and, to be honest, Catalysts' are better.
That said, I *am* going to release the source with V3, and I may make a tutorial for opening up the character sheet in Inkscape to get what you want to get. For the most part it's pretty simple-the text is an epic pain, since PDF formatting =/= SVG formatting, which is what Inkscape wants. A printer-friendly version is rather low on my priorities list; even though it would be nice, form-fillable is sort of antithetical to it. That said, making one once I reach a certain degree of progress would be pretty simple.
As far as the "vital statistic" page, I am going to include at some point just a blank multi-line field that you will be able to put whatever you want in, but it won't allow calculations or the like.
