+### Notes
+* Until a custom filetype can be set, a global variable `vim.g.inside_lf` is used to indicate that the file manager is running
+
 ### TODO
+- [ ] Set custom filetype (filetype inheritance?)
 - [ ] `:LfToggle` command
 - [ ] Save previous size when terminal is closed, so it is restored on open
 - [ ] Set Lualine to `Lf` title
