org-xournalpp VS C4-PlantUML

Many packages like org-krita/org-yt/org-excalidraw/org-xournalpp allow custom files to be displayed inline by means of a custom link type. However, they don't work when the file is linked as an attachment, which makes me think that there may be a better way to achieve this.

By Xournalpp-mode do you mean org-xournalpp? I was not able to find a package named Xournalpp-mode.

When writing in org-mode (most of my research writing) I use org-xournalpp to add rough sketches and figures.

I haven't had a chance to try it out but you might be interested in https://github.com/lepisma/org-krita and https://gitlab.com/vherrmann/org-xournalpp

Third this. Don't look any further, just do it!

Also, PlantUML + C4 is like peanut butter & jelly:

I'll gladly give up control of layout, and accept some ugliness, to never again have to worry about dragging boxes and arrows to be pixel-aligned, and then do it all over again when I add another box...

It looks like Mermaid has C4 support too:

C4-PlantUML: Export your model as C4-PlantUML diagrams.

PlantUML + C4 plugin;

Yes. I use this all the time for software diagramming. With c4 model (https://github.com/plantuml-stdlib/C4-PlantUML) and AWS icons (https://github.com/awslabs/aws-icons-for-plantuml)

The C4 model (https://c4model.com/) is great for architecture diagrams. You can use different tools to generate them. Here are the ones I've been using:

3️⃣ Text-based diagramming- C4-PlantUML

> onboarding docs

yes, they're don't changing frequently

> system design docs

yes - see C4-PlantUML[1]

> meeting notes

no, unless they're directly code related like ADRs [2,3].

Although one can abuse Github Issues + comments for this, in my opinion it's better to use modern SaaS tools for this, i.e. Loom, Descript, Linear.app, etc. - you can automate this process, e.g. transcribe the meeting's recording and add the issue/repo using Github Actions.
