-## TODO
+## TODO 1
 - Tree creation should be async
-- better error checking when fs updates
 - sneak like cd command to find a directory
 - better default colors (use default vim groups)
 - give user option to choose for file generation command
 - command to find current file in the directory structure
+- refactor all `system` call to `libuv` functions, with better error management
 - create proper highlight groups or add highlight function to give the user ability to setup colors themselves
 - bufferize leafs of node being closed so when opening again the node, we open every directory that was previously open
-- use libuv functions instead of `touch` and `mkdir` in `create_file()` and allow file creation with path like `foo/bar/baz`
 - better window management: 
   - check tree buffer/window for change so we can avoid it being resized or moved around or replaced by another file
   - monitor window layout in current tab to open files in the right place
   - add `<C-t>` to open buffer in new tab
 > this might be a little hard to implement since window layout events do not exist yet
