Making one sheet work in multiple languages. Its very tedious to set up, but a lot simpler with Templating (see below).
More Speculative Stuff
These are things which are only added to a sheet in certain cases, and might not even be possible in come cases. These will probably be created gradually throughout 2024 (but I have some other massive projects in mind that might consume my time).
A charactermancer is only possible if you have the license for the system. I’ll probably write it up eventually, but its not a high priority.

Coming one day (probably – it’s turning out to be less useful than originally envisaged, but Roll20 did state improvements were coming).
Custom Compendiums are something Roll20 have said will be available, but they do not exist yet. If they do become available, I’ll add instructions here.
Sheet Templating is a way to create sheets more rapidly, by scripting the repetitive parts. There’s no right way to do this, and several options.
