+### Perf / Fixes
 - Tree creation should be async
-- 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
+
+### Features
+- sneak like cd command to find a file/directory
+- better default colors (use default vim groups)
+- create proper highlight groups or add highlight function to give the user ability to setup colors themselves
+- add `<C-t>` to open buffer in new tab
+
+### Window Feature
 - 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
