Step 4 done!
I’m coming back to this project after a week or so, and I realised I finished step 4 without writing a devlog, so here it is.

Since my last devlog I’ve completed:

1. Added a “app” to the desktop
2. Made the icon clickable
3. Created my first app window/app
4. Personalised according to me

The guide was a bit vague this step, so I don’t know how many errors I’ve made so far, but I’ll leave that for the final devlog.
