 - LSP easy setup. Support some of the most commonly used lsp client setup
 - Unorthodox UI with floating windows
+- Async request with lsp.buf_request for reference search
+- Treesitter symbol search. It is handy for large file (Do you know sumneko_lua has 100kb size limitation?)
 - fzy search with Lua-JIT
 - Better navigation for diagnostic errors, Navigate through files that contain errors/warnings
 - Group references/implementation/incomming/outgoing based on file names.
