- the numpad functions are reorganized, and there are more of them now,
so the numpad can be treated either as something that's toggled or
something that's locked
- the numpad functions may need to be split into a separate file, to
keep things pretty. i'll look into it later.
- the linked-list functions are being written so that hopefully i can
change the concept of how layers (with transitions and masking) are
handled. they're incomplete in this check in because i took a break
to fix the numpad functions for dox
