myView

Share several monitors at once in a video call.

Download myView-0.2.2.zip

v0.2.23.9 MB Requires macOS 26.4 or later on Apple silicon

Three displays composed into one picture. The middle display is large and in front; a tall display on its left and a small one on its right stay visible behind it.
What the call receives in the Desk layout. The display you are working on comes forward and the others stay in view. Screen contents here are placeholders.
Twelve seconds of the picture following you from one display to the next. No sound.
One display fills most of the picture. The other displays sit in a column on the right.
The Spotlight layout: one display large, the rest in a rail beside it.
The myView window. On the left, the live picture, a map of the desk and the five layouts. On the right, the list of displays and the controls for following, the Lens and the output.
The main window while live: the picture going out, your desk, the layouts and each display’s controls.

myView puts the monitors you choose into one 16:9 picture. Your meeting app sees it as one more screen: share that screen and you are sharing all of them. The people on the call see your whole desk, and the display you are working on stays large enough to read.

Five layouts arrange the displays: Desk, Spotlight, Split, Inset and Solo. The spotlight follows you to the display where you click, type or scroll, and the Lens frames the active area when text would otherwise be too small. To keep something private you can blank a display, hold the picture, or press a panic key.

Used in real Google Meet and Discord calls, where the person watching could read the text. FaceTime is intended and not yet tested.

After you download

  1. Unzip the download and move myView to your Applications folder.
  2. Open it and allow Screen Recording when macOS asks.
  3. In your call, share your screen and pick the one named myView.

Preflight

See what is weighing on your Mac and prepare it for what you do next.

Download Preflight-2.0.1-arm64.dmg

v2.0.14.1 MB Requires macOS 14 or later on Apple silicon

Preflight watches CPU, memory pressure, swap, disk, network and power, and temperature where it is available, and explains what it sees. Choose a workload such as development, meetings, creative work, local AI or gaming, and it draws up an exact list of processes to stop while keeping the work that workload needs.

Nothing stops until you have reviewed the list and confirmed it. Apps get a normal quit request; force quitting is a separate, deliberate choice. Afterwards Preflight shows what it measured before and after. It does not clean caches, add memory or promise a faster Mac, and a healthy Mac may need no action. History stays on your Mac.

After you download

  1. Open the disk image and move Preflight to your Applications folder.
  2. Open it. Preflight lives in the menu bar.

Yardgoat Caboose

A planning and memory system for repositories worked on by AI agents.

Set this up in my repo: https://yardgoat.ai/caboose.md

v1.0.0Paste it to your coding agent.

Caboose gives a repository one roadmap that always answers three questions: where have we been, where are we, and where are we going. The repository itself remembers, so any agent, on any model, can pick up where the last session stopped.

You paste one line to your coding agent. It reads the specification, surveys the repository’s real history and drafts the roadmap, numbered plans, decision records and checks. Then it stops: nothing is carried out until you say so.

Caboose is the first public part of Yardgoat, a larger system still in development, and it stands on its own. The whole specification is at yardgoat.ai/caboose.
