 @TODO:
-- trigger characters (with setting)
+- fix unicode_utf8_to_utf32 to handle bad UTF-8 (i.e. continuation bytes which aren't actually continuation bytes)
+- provide completion context?
+- dont do completion if provides_completion = false
 - scroll through completions
 - only show "Loading..." if it's taking some time (prevent flash)
 - LSP setting
 - figure out workspace
 - make sure "save as" works
+- more LSP stuff:
+     - go to definition using LSP
+     - find usages
 - rename buffer->filename to buffer->path
     - make buffer->path NULL for untitled buffers & fix resulting mess
 - run everything through valgrind ideally with leak checking
