 - FEATURE: Add `tab:> ` to 'listchars' option when `options.extra_ui` is set. This prevents showing `^I` instead of a tab and actual value comes from Neovim's default.
+- FEATURE: Set `termguicolors` only on Neovim<0.10, as later versions should have it on by default (if terminal emulator supports it).
