Might be nice to mention the presence of Servo folks at FOSDEM and the 2 talks we have there: #offtopic > Fosdem 2026 @ 💬

Would it perhaps make sense to make a small video on how to use multiple windows? At least to me it was not 100% clear at first. It might help to show that one needs to first create a new window (that is still docked) with the small + sign, and then one can pull the window away from the docked thingy to get real dual windows.

what platform is this on? on linux at least, there’s a separate button for new window, and you must click that to create a new window. as far as i can tell, there’s no way to take a tab(?) and break it out into a new window.

That was on macos, but since this is the desktop port based on egui, I would assume it's the same on other platforms.
There are two rows of tabs - the one at the top are the "windows" tabs and then each window also has tabs. The top-level window tabs can be pulled and detached from the main window, creating two separate windows, that show concurrently (as opposed to the tab-like behavior when creating the new window).

wow, i had no idea. could you please show me what that looks like? doesn’t have to be polished enough for the monthly update for now, i just want to understand it better.

trying to find any documentation about this feature, or a corresponding change in egui or winit, but so far no luck. i also checked the 2025-12-31 nightly on macOS 15 intel, since i don’t have macOS 26 set up right now, and i can’t reproduce this behaviour, so unless this is a new macOS 26 feature, i wonder if it’s some third-party software on your machine? in the meantime, i can ask around and find someone to try it on macOS 26.

[jschwe]

Ah, it seems to be a macos setting - I wonder if I changed that myself.

System Settings > Desktop & Dock > Windows setting for "Prefer tabs when opening documents," which can be set to Never, Always, or In Full Screen

[jschwe]

It's interesting because it is set to always, but Firefox, Safari and VSCode seem to ignore it and actually open new windows. RustRover / Jetbrains IDEs are the only software I used where it actually shows.

i wonder if those apps that ignore it are actually respecting the setting, but doing so with their actual tabs to avoid duplicate tabs… anyway, i can now reproduce it on macOS 15. i’ll create an issue.
