The weekly email
What the vibeheatmap email looks like
One email every Monday: the week's heatmap, the fastest-rising kinds of projects and one standout project. This is the latest one, as sent.
Heatmap Sep 28 – Oct 4: Desktop window and dock utilities up 76%
subject line2,505 newly shared projects from 9 builder subreddits, week of Sep 28 – Oct 4, 2026.
Worth a look: The MacBook notch and lid as an interface
Desktop window and dock utilities was the fastest-rising group over the last 4 weeks. A cluster inside it treats the edges of Mac hardware as places to put interface: the notch becomes a tray, and the lid's angle sensor drives screen animations.
- Tack+: a notch panel for music, messages, clipboard history and files
- ILoveNotch: a hover-activated tray in the notch
- MacBook Duo: a folding animation driven by the lid angle
- GlassFold: a frosted-glass sweep as the lid opens or closes
Worth investigating: Which of these save a step people take many times a day, and which are novelty? Compare what each puts in the notch and how it is opened.
A lead to explore, not evidence that customers will pay.

How to read this: We count the projects builders share on Reddit each week. A project is counted once, in the week it first appears in our sources — that’s not necessarily when it was built or launched. Because some weeks are busier than others, we compare each topic's share of all projects, not raw counts, so a busy week doesn't make everything look like it's growing. “Up 70%” means a topic is taking up 70% more of the conversation than before.
