add mini-edit-external it's bound by default to C-x in the minibuffer keymap. It'll open an external editor to edit the content of the minibuffer. When the editor exits, we'll call the completion function with the content of the file. Stuff inputted with an external editor are not persisted to the history thought. That would require the UI to handle multiline strings which is currently impossible.

cmd: introduce toggle-styling This adds a new command `toggle-styling` which toggles the formatting between the defaults (or anything specified in a configuration file), and the "raw" prefixes as defined in the gemini file.

add cmd_search to search using a search engine This adds a new command `search', bound by default to `s', that prompts for a query and loads and consult the ``oracle'' (the search engine) using default_search_engine (which will be made customizable.) It also temporarly supports only gemini URLs. Feature requested by -fab-, thanks!

tweak client-certificate-info description avoid the word "use" since it's better to show first use-certificate instead of this niche function.

add unload-certificate to stop using a certificate

load and optionally remember client certificates This adds use-certificate, a user function to start using a certificate or switch to a different one. It asks whether to persist the certificate, if not it will only be used for the current session. use-certificate is implicitly called when the server replies with a 6x status code.

fix typo in push-button-new-tab description

move includes back to the root directory Splitting stuff into sub-directories was just a big mistake.
