Notes
How to use Lumeira, what it is good for, how it is built, and what changed in each version. New pages land here as the app grows.
News
What is happening with Lumeira.
Guides
How to do one thing in the app, start to finish.
- Guide
Browse a folder without touching the mouse
The keys you need for going through a folder fast, and the two that people miss.
- Guide
Compare images side by side
K puts this image and the next one next to each other. Arrow keys move the pane you pick.
- Guide
Folders, siblings, and the permission question
Why macOS asks about the parent folder once, and what Lumeira can and cannot see.
Use cases
A whole workflow for one kind of work.
- Use case
Go through 500 AI generations in twenty minutes
A workflow for the output folder from Midjourney, ComfyUI, or Stable Diffusion: keep the good ones, trash the rest, do not lose the seeds.
- Use case
Pick the best of four variants
Same prompt, four seeds, one decision. Put them in a grid and zoom into the same spot in all of them.
Engineering
How the app is built, for people who like that.
Findings
Things we learned the hard way while building it.
- Finding
Clicking a pane did nothing, twice
SwiftUI tap gestures do not reach a Metal view that handles its own mouse events. Scripted clicks do not either. Real ones do.
- Finding
A keyboard shortcut that never fired, and why
Shift plus a punctuation key looks like any other menu shortcut. AppKit disagrees.
