Configure the Emacs Tab Bar. Add the appropriate formatters via TAB-BAR-FORMAT. The default ones allow you to place "modules" (i.e. menu items constructed by the helper make-rde-tab-bar-module) arbitrarily on each side of the bar, but you can also include built-in formatters such as tab-bar-format-tabs.

The examples below show different types of modules:

(make-rde-tab-bar-module
 :id 'text
 :label "My arbitrary text")
(make-rde-tab-bar-module
 :id 'battery
 :label 'battery-mode-line-string)
(make-rde-tab-bar-module
 :id 'notifications
 :label '(:eval (rde-ednc--notify)))

Configure emacs for guix usage and development.

Enable completion-preview-mode, a built-in Emacs 30+ feature that shows inline completion suggestions as you type.

Configure Emacs Dashboard, an extensible startup screen. Choose whether to be prompted by the dashboard on startup by setting SHOW-ON-STARTUP?. Set up the visible sections via ITEMS, where each entry is of the form (LIST-TYPE . LIST-SIZE). See dashboard-items to get an idea of the format. For the aforementioned to work, you also need to configure ITEM-GENERATORS, where each entry is of the form (LIST-TYPE . LIST-GENERATOR-FUNCTION). You can quickly navigate to each section with ITEM-SHORTCUTS and set a custom name for each one via ITEM-NAMES.

NAVIGATOR-BUTTONS are custom buttons that you can display below the BANNER, to include quick shortcuts to things like web bookmarks. BANNER can be either `official' for the official Emacs logo, `logo' for an alternative Emacs logo, #f to hide the banner, or a custom file path to an image whose dimensions you can constrain with BANNER-MAX-HEIGHT and BANNER-MAX-WIDTH.

Remind yourself of tasks by setting DASHBOARD-AGENDA-WEEKLY? to #t and customize the format of task entries with DASHBOARD-AGENDA-PREFIX-FORMAT (see org-agenda-prefix-format for information on the format strings).
