-A modular dark desert-themed colorscheme and status line for Tmux with warm, earthy tones and multiple palette variants (13 Total Themes). Originally inspired by the classic `desert` theme for Vim. This plugin provides a fully styled status line with a robust dynamic mode indicator for **ALL** of tmux's modes (like Vim).

-## Features
+## Status Bar with Dynamic Modes
 
-- **13 theme variants**: Covers the entire rainbow of options with an emphasis on being dark. Variants are all desert-inspired.
-- **Automatic theme loading**: Set `@oasis_flavor` and the system will handle the rest
-- **Advanced status line**: Dynamic mode indicators with color-coded states inspired by `vim` for each of tmux's modes: includes `NORMAL`, `COMMAND`, `COPY`, `VIEW`, `CHOOSE`, `CLOCK`, and `OPTIONS` modes.
-- **Modular design**: Separate theme files and unique status line configurations (_you could just download **only** what you need_)
-- **Standalone**: Zero dependencies on any other plugins
+Wouldn't it be nice to know what mode you're in? And not just one mode, but for **ALL modes like in Vim**.
