1. No 2. Aerospace has significant performance issues with workspaces. The problem has persisted for over a year, and there are no plans to fix it. That's why I started building…

Lightweight alternative to tiling managers
From 2 comments
I have been using AeroSpace for this purpose for over a year. I simply disable all the tiling features in the config and only use two shortcuts: switch to workspace and move…

Objections
Cannot assign different windows of the same app to different workspaces
From 2 comments

Hides apps not assigned to a workspace
From 1 comment
I've started trying out this app, and I'm really confused by why it hides applications that are not in the space list. For example, let's say I have defined a "Work" space and…

Support multiple windows of the same app per workspace
From 2 comments
The biggest pain point with macOS spaces is how it handles multiple windows of the same app. It drives me crazy. What is FlashSpace’s approach for solving this?
matanrubin on HNThis is SO close to being perfect for what I'm looking for. I just need better support for handling multiple windows of the same app in a workspace. Is there a way to create a…

Support for Windows

Is there a similar app for Windows? I work at Microsoft and while I'm allowed to use other OSes it's not really practical.

Does it require disabling SIP?

This looks great! I currently use Aerospace, but your usage of macOS spaces has me curious. 1. Does FlashSpace require disabling SIP? 2. Aerospace documents the limitations of…

Does it handle browser window restore across Spaces?
From 1 comment
Will this, or anything else, make Safari restore its windows to the spaces they were in when it quit? Chrome does better but only succeeds part of the time. This is so annoying…

Is this compatible with Amethyst? I want tiling windows but without the delay in switching spaces.
