svg-tag-mode VS mu4e-dashboard

That is a module that let's you replace occurances of regexes with svgs (https://github.com/rougier/svg-tag-mode)

https://github.com/rougier/svg-tag-mode is one ingredient, which makes org documents look more fancy.

You're looking for svg-tag-mode. It's on ELPA and MELPA, so you should be able to just use-package one of those (don't forget to package-refresh-contents).

tag looks like from https://github.com/rougier/svg-tag-mode/tree/07640c97a1dcc305010a384fffdaa7788c342da7

I agree, that's a really great example. It would be even more natural for tags in org-mode, which already supports drawing tags away from the text itself to a far-right column, but they really could be moved in the other direction to the left of a hairline next to the bullets, and they'd be more readable.

BTW, Nicolas has a lot of interesting packages exploring use of graphical design elements in Emacs apart from the Nano Emacs stuff; for example, there's https://github.com/rougier/svg-tag-mode. I love how he chooses to represent dates and dates with times attached, and to distinguish active vs. inactive dates with shading rather than "[" and "<". That actually makes it easier to spot a common org-mode mistake without having to call up the agenda.

It's here: https://github.com/rougier/svg-tag-mode/blob/main/examples/example-2.el (just evaluate the whole buffer)

Specifically this is the one: https://github.com/rougier/svg-tag-mode

Inspired by Nicolas Rougier's mu4e-dashboard, I tried to create a similar dasboard for my org-agenda. The links in the dashboard open an agenda search window in the middle window, which by default shows a weekly agenda. This combined with the side window on the right (mostly taken from Rougier's task agenda) makes for a rather nice setup, I believe.

Sidebar is a child frame that is displayed on the left side of a regular frame and can be used to display any kind of information. In the screenshot above, it displays a mue4e dashboard (https://github.com/rougier/mu4e-dashboard) . I did not find how to have per-frame theme and I ended up exploiting the dark/light mode frame settings and theme will adapt (if it includes the two modes). Here, the theme here is nano-theme (https://github.com/rougier/nano-theme) and the sidebar uses the dark version.

My weird idea is that I think Emacs could be a great platform to ship software. Just like people use Electron to ship apps, we could use Emacs to ship apps as well. We would have a great power for customization. We have buttons (widgets) that can be a little hard to understand at first, but dashboard-mode and spacemacs are good examples that we can have beautiful "interfaces" in Emacs. Look at mu4e-dashboard, we could have a very beautiful and functional email software in Emacs someday, we just need an easier way to setup email because it can be really painful.
