I notice that when I use Gems in Gemini _(which is just a project like in Claude)_ and I upload some files, if I then reload the page, it will often duplicate the same files.

Gemini 3.1 Pro is good, but the UX is so much nicer in Claude and Sonnet 4.5 is just as good at coding.

The token strategy did not make much of a difference, but replacing `.onAppear` and `.onDisappear` with `.onReceive` worked. I also decided to use `MergeMany` instead of having one `.onReceive` for each notification (there are many).

Think I have found the issue.

It's most likely the way I use `removeObserver`. I need to pass the observer token to `removeObserver` to make sure the correct observers are actually removed. This means I need an array to keep track of the many tokens from all the different formatting notifications.

I'm getting a leak somewhere in my formatting notifications (I use `NotificationCenter`).

This is causing problems if I have two note documents open in the same window.

For example, if I change the block type from text to a heading in one of the notes, then save and go to the other note, it will have completely overridden the data.

I appreciate that Apple provides all the properties you can call on `NSGlassEffectView` like `tintColor`. In my case I applied a black color with 50% opacity - looks really good. Would like to have t...

I have long wondered if there are some private APIs to control the opacity and blur radius of the `NSVisualEffectView` 🤔

I have seen apps _(like Warp terminal)_ that allow the user to control these values.

Apparently using `.glassEffect()` on the window background will break the functionality of the `.onDrop()` modifier. I wanted the Liquid Glass effect on the window background of my app, so I added th...

Would like to have the same options for `NSVisualEffectView`…

I wanted the Liquid Glass effect on the window background of my app, so I added the `.glassEffect()` modifier which worked, but then I could not drag-and-drop files in the infinite canvas anymore…

Turns out that you need to use the AppKit class called `NSGlassEffectView` instead. Now the `.onDrop()` modifier works again.
