Ok, I've packaged up the appropriate .user files and made sure everything is set-up so the names don't conflict with what's in the base install for anyone who wants to play around with these (I know I will be!) the dossiers.user file is where you can name what your sheets will be and if you needed to add pages that's the place to do it. Then you'd need to follow the format of the sheet_mine1.user and sheet_mine2.user file (making a sheet_mine3.user file, for example.)
There are plenty of comments in the files from LWD so hopefully those will act as a good guide for how to play around with these. They should install in your data/savage directory and are available from
https://www.dropbox.com/s/bt5sh2halfy4sik/Sheets.hl. So hopefully we can get some folks here checking into these and making up some cools sheets for whatever folks might need them for. And if you do, please share!
And thanks again to Mathias for pointing this out. I never realized we could do things this way!
