    Flatland

    Flatland

    Flatland is a simple theme and accompanying color scheme

    Flatland is a popular UI and syntax theme originally crafted for Sublime Text that embraces a flat, modern aesthetic with crisp contrast and saturated accent colors. The theme pairs a minimal chrome with clearly distinguished syntax groups so tokens remain readable without visual clutter. Its palette favors warm oranges, cyans, and purples against dark backgrounds, striking a balance between vibrancy and long-session comfort. Flatland also standardizes iconography and tab styling to keep the editor frame unobtrusive, letting code take center stage. Because it became widely adopted, many ports exist for other editors and terminals, making it easy to keep a consistent look across tools. The project is opinionated but pragmatic, aiming for a cohesive, contemporary feel that still respects legibility and focus.

    vim-startify

    vim-startify

    The fancy start screen for Vim

    vim-startify is a plugin that replaces or enhances Vim’s default blank start screen (when Vim is launched without files) with a more structured, usable homepage. On starting Vim, it presents a menu showing recently edited files, bookmarked files or sessions, and optionally saved sessions that can be resumed. The menu is navigable, and you can choose entries either by selecting with cursor keys or simply typing the bracketed number next to the item. Additionally, the plugin supports configuring custom headers/footers (for example with ASCII art or useful information) and even opening multiple files at once via the menu. This startup experience enhances productivity by giving immediate access to recent work or commonly edited files, reducing the need to type paths manually. It also supports sessions, so you can quickly restore your editing environment (splits, buffers) for a project.
