Open two different projects in the same window (MacOS Big Sur)
已回答
Hi,
lately I've been experiencing some curious problem with IntelliJ.
I have two java projects opened by default everytime i open the IDE, but IntelliJ randomly opens them in the same window or in separated ones.
Is there a way to open them always as one window with more tabs?
Thank you,
Michael

Hi everyone,
I have the same issue with WebStorm.

Mnatale See? Looks like a mass conspiracy against tab
Did you notice a relation of the issue to the full-screen mode of the IDE?
How the "System Settings | Dock | Prefer tabs when opening documents" option is set?
Seems similar to https://youtrack.jetbrains.com/issue/IDEA-255898
Are you about this feature (different projects in one window)?

It's not working since I upgrade to PyCharm 2020.3 (Professional Edition) Build #PY-203.5981.165, built on December 3, 2020
Does anybody know how to enable it again? It's really useful feature for me.
It was not a feature, but a bug caused by the macOS update.
Here is the feature request for multiple projects within one window: https://youtrack.jetbrains.com/issue/IDEABKL-6118
Anton Uspehov yeah that's exactly what I meant.
HI can you teach me how to open different projects in one window as showed in your picture?@Anton Uspehov
This is really cool feature/bug... Please return it
With PyCharm, follow the two steps (inspired by @Konstantin Annikov):
1. open the first project and enter full-screen mode
2. open another project in a new window
Works in PyCharm 2020.3.3 (Community Edition).
Mc Deng, thanks, it's work!
Very cool feature/bug - it will be cool to see this feature in next updates not only on macOS devices
I use Window > Merge All Project Windows, then it will merge all project windows into one. In the window, I can switch projects by tabs.
Teddy Lee Thanks it works like Anton Uspehov's window
