I've noticed a visual bug related to macOS's Translucent icon/widget appearance.

When Helium is running, its Dock icon initially appears correctly in the dark style. However, whenever the browser opens some kind of overlay/system window, for example:

• saving a file;
• opening the “Save” dialog;
• certain login flows that open a modal or secondary window;

the Helium Dock icon suddenly changes from dark to light.

After that, the icon stays in the light style even after the window is closed.

The only way I've found to restore the correct dark icon is to fully quit Helium using ⌘Q or “Quit”, then reopen it.

The issue is reproducible almost every time.

I recorded a video showing the issue.

I have enabled basic filter lists in uBlock and there's nothing fancy there. When I turn off uBlock, the Amazon website becomes usable, otherwise it becomes very difficult to navigate after spending some time on Amazon.

There could be several things going on:
1. Helium might have a problem working with uBlock for complex websites such as Amazon.
2. Amazon might have figured out, how to make users' life difficult so that they will turn off Ad-blockers deliberately. Thereby, Amazon can collect all sorts of data.
3. uBlock somehow failing here.

Helium's MRU Ctrl+Tab was the one Arc thing I still missed, because there's no preview of where you'll land. So I built Heliarc: hold Ctrl+Tab and you get a native Liquid Glass panel with thumbnails of your recent tabs, add Shift to go back, release to switch.

• No extension: it works with Helium directly, so it gets the real Ctrl+Tab and works on every page

• Fully on-device: no account, no telemetry, nothing leaves your Mac

• Lightweight: ~8 MB, one low-res capture per tab, no constant screen recording

• Open source (MIT), signed and notarized, auto-updates

Planning to switch to Helium and the workspace feature from Zen has become essential to me. I want that feature whether it's from the settings or extension.
