Hey! Taking the liberty to answer you as the person behind the SRD and such.
Which platform(s) do you consider a good alternative for Character Sheets like this?
I can confirm there is a fillable (colored) version of the Character Sheet coming out with v1.1 (The images are already available on our Discord, although the fillable PDF part is not done yet)
I'm an Obsidian User as well, I'll see what I can do to make a cool datatable sheet or something there at some point, sounds like a good idea!
