2025 has been one busy year for me! I feel as though I've been working on a dozen things at once and have spent much of my working (and personal) days productively. Miracle finally feels like it's getting somewhere fast, the Flutter multi-window work is landing at a solid pace, and Mir is feeling like a truly solid option for Wayland compositor development. I will refrain from speaking too much on the Flutter and Mir work in this post, as those are best left in the hands of Canonical.

2025 has been a whirlwind of a year, and I'm sure that 2026 won't slow down at all for me. A lot of the long term projects that I've been working on are finally coming together, and I feel as though I am on the cusp of making software that I'm truly proud of. On top of that, I am engaged! What a time to be alive :) I hope you all have a lovely New Year with your friends, family, cats, dogs, and everything else.

I've recently fallen in love with <code>org-mode</code>, specifically when I use it with <a href="https://www.orgroam.com/">org-roam</a>. I find the whole workflow of creating, tagging, and - later on - searching for information on my computer to be very elegant. On top of that, now that I have the time, I want to begin writing blog posts to better work out my thoughts. With both of these things in mind, I am again turning to the universal tool for human prospering: <code>org-mode</code>.

Next thing on our list is custom styling. This can be achieved by first installing the <code>htmlize</code> package from <code>melpa</code> / <code>elpa</code>. The EmacsWiki describes this as "a package for exporting the contents of an Emacs buffer to HTML while respecting display properties such as colors, fonts, underlining, invisibility, etc" (<a href="https://www.emacswiki.org/emacs/Htmlize">reference</a>). If used "out-of-the-box", the buffer will be exported to HTML with all of the styles inlined (e.g. if you underline something in your org file, you will generate a <code>&lt;span style="text-decoration: underline"&gt;...&lt;/span&gt;</code>). However, we are more interested in styling everything by ourselves: we don't want <code>htmlize</code> making assumptions about what underlining means to us! Luckily, <code>htmlize</code> gives us the option to export with class names instead of inline styles so that we can specify each style for ourselves.
