Hey — it’s James
Ever since I was a kid, people kept telling me how lucky I was. Luck in the Gladstone Gander (Gontran Bonheur) kind of luck. Finding random bills on the street. Falling out of trees, getting crushed by a massive old wardrobe, or even being hit by a car—and walking away without a scratch. Lucky in games, lucky at school, lucky in sports...
I’ll never know how true that all was—luck isn’t something you can really measure or compare. But what I know for sure is that…

3 Tips / Updates
1/ GPT 4.1 powers Notion Mail
Notion Mail AI features are now powered by OpenAI's latest model: 4.1
Quick reminder: When you activate AI on your Notion plan, it automatically works for Notion Mail too—one subscription covers all devices.
2/ Full width in Layouts
There’s one thing many of us overlooked when the Layout feature went out. I’s the ability to apply globally full width to all pages from a same database. Before, if not using a database template, we had to do it manually for every new page. Good news is, you can still override this setting if you change the width of a specific page manually.
To find the feature, go to Customize layout
→ Page settings
→ Full width

3/ Notion Mail notifications
Notion Mail desktop notifications are coming! Thoughts? I'll personally be skipping these little pop-up boxes—they stress me out too much 😬

2 Resources
1/ NotionApps
NotionApps is—as you can guess from its name—a tool that lets you transform a Notion database into a mobile app. Instead of sharing a Notion page, you can easily create public or private apps for use cases like client portals, internal tools, directories, or field apps.
It's perfect for people who don't need or want to use Notion but still need to access the information.
2/ Tabs—Thomas Frank
Tabs has been everyone's fav new feature in the Notion ecosystem. For real-world examples and a deeper dive, check out Thomas Frank's video ↑
